Reflex Active Interchangeable Strap Calling Smart Watch
Reflex ActiveMost smartwatches under £50 make you choose between decent fitness tracking and genuinely useful smart features. The Reflex Active Interchangeable Strap Calling Smart Watch tries to close that gap by putting hands-free calling — a feature usually reserved for pricier wearables — on a wrist-worn device that costs about the same as a round of drinks. Add in swappable straps, a full suite of health sensors, and a battery that's meant to outlast most premium watches between charges, and you have a product that looks, on paper, like an outlier in its price bracket. The real question is whether it delivers on that promise in daily use, or whether the low price explains itself once you start wearing it.
Design and Build: Light, Swappable, and Built for Daily Wear
The case is made from a lightweight polymer rather than metal or glass, which keeps the whole unit at roughly 70 grams — light enough to forget you're wearing it during a workday, though it also means the watch feels distinctly plasticky rather than premium when you look closely. At 45mm tall, 39mm wide, and just 9mm thick, the profile is slim enough to slide under a shirt cuff without snagging, and it will sit comfortably on most adult wrists thanks to a strap sized to fit wrist circumferences between 125mm and 205mm — that covers the vast majority of people, from slim wrists to larger builds, in a single size.
The included silicone strap is soft against the skin and designed for all-day wear, and the watch ships with two additional straps in blue and grey so you can switch colours to match an outfit or just freshen up the look when the original starts to show wear. Swapping straps is a genuine differentiator here: because the bands are designed to be removed and replaced, you're not locked into one colour scheme the way you are with most watches in this price range, where the strap is usually fused or difficult to change without tools.
Personalisation extends to the screen itself. The watch supports interchangeable digital watch faces, and you can upload your own photo to use as a face — a nice touch for anyone who wants the watch to feel less like a generic gadget and more like something personal.

The Display: Straightforward, Not Flashy
The screen measures approximately 1.8 inches across and uses TFT (thin-film transistor) touchscreen technology rather than the AMOLED panels found on pricier smartwatches. In practical terms, that means colours and brightness are perfectly serviceable for reading notifications, checking the time, or scrolling through menus, but you won't get the inky blacks or the vivid contrast that AMOLED displays deliver — and outdoor visibility in bright sunlight will likely be a notch behind higher-end alternatives. The upside of TFT is that it's cheaper to produce and generally less power-hungry in always-partial-use scenarios, which plays into the watch's battery story. Touch navigation itself is simple: swipe between menus and tap to select, following the pattern nearly every smartwatch owner already knows from years of using a smartphone.
Hands-Free Calling: The Feature That Sets This Apart
This is the headline act. Thanks to Bluetooth 5.2 connectivity, the watch can make and receive phone calls directly from your wrist once it's paired with your phone — useful when your hands are full, when your phone is charging across the room, or when you simply don't want to dig it out of a bag or pocket every time it rings. You can answer, decline, or manually dial through the watch's interface, and mid-call you're able to switch the audio back to your handset if you'd rather finish the conversation there.
The trade-off to understand upfront is range. Bluetooth calling on watches like this typically works within about 10 metres of your phone, so if you walk out of that radius — into another room, out to the car, down the street without your phone — the call and connection will drop. It's a hands-free convenience layer on top of your existing phone, not a standalone cellular device; there's no SIM card involved, so you can't make calls independently of your paired phone being nearby.
Health and Fitness Tracking: What You Can Actually Measure
Underneath the calling feature sits a genuinely comprehensive set of wellness tools for the price:
Heart rate monitoring — tracks your pulse throughout the day and during workouts, useful for gauging exertion levels or simply keeping an eye on resting heart rate trends over time.
Blood oxygen (SpO2) tracking — measures the oxygen saturation in your blood, a metric increasingly common on fitness wearables and useful for general wellness awareness, particularly around sleep quality and altitude activities.
Sleep analysis — logs your sleep automatically overnight, giving you a picture of how long and how well you're actually resting, which is often more revealing than people expect.
Step counting and calorie tracking — the fitness-tracker basics, letting you set and monitor daily activity goals.
Multiple sports modes — dedicated tracking profiles for different types of exercise, so a run, a cycle, or a gym session can each be logged in a way that's relevant to that activity.
For anyone starting a fitness habit or just wanting a general sense of their daily activity and sleep patterns, this covers the essentials without requiring a subscription or a second device. Where it's worth tempering expectations is accuracy: sensor-based tracking at this price point — on this watch and its category peers alike — tends to be a useful trend indicator rather than a clinical-grade measurement. If you need precise athletic metrics for serious training, a dedicated sports watch will out-measure it.
Battery Life and Charging: How Often You'll Actually Plug It In
The battery is rated for up to four days of typical mixed use — meaning notifications, some calling, screen checks, and health tracking running throughout the day — stretching to as much as ten days if you dial back usage to occasional glances and minimal calling. A full charge from empty takes about three hours. In real terms, that means most people charging it once every few days, likely alongside their phone overnight, rather than needing to top it up daily the way some smartwatches demand. It's not going to match a basic fitness band that can go two or three weeks between charges, but for a watch that's actively handling phone calls and a colour touchscreen, four-plus days is a genuinely solid outcome and comfortably ahead of what many smartwatches — including some considerably pricier ones — manage with similar features switched on.
Water and Dust Resistance: What's Actually Protected
The watch is built to resist water and dust, so you can wear it through rain, sink splashes, sweat during a workout, or a spilled drink without concern. What it isn't designed for is submersion — this is not a swimming companion, and dunking it in a pool or taking it in the shower runs against how it's rated to perform. If swimming tracking matters to you, this isn't the watch for that particular use case; treat the water resistance here as protection against everyday accidents and weather, not as a green light for water sports.
Smart Features: Notifications, Music, Weather, and GPS
Beyond calling, the watch pulls through smartphone notifications so you can glance at messages and alerts without pulling your phone out, gives you basic music playback control from your wrist, and displays weather updates once synced with your phone. It also includes GPS support for tracking routes and distance during outdoor activity. Worth noting: many watches in this price bracket rely on your paired phone's GPS radio rather than a standalone chip inside the watch itself, so if that's the case here too, you'd want your phone within range during outdoor sessions to get accurate location data — a reasonable assumption for a device at this price, though it's a detail to keep in mind if standalone, phone-free GPS tracking is a priority for you.
The watch pairs with a free companion app, available on both the Google Play Store and Apple App Store, which is where you'll manage notification settings, browse additional watch faces, review your health data in more detail, and handle firmware updates.
Setting It Up: App and Phone Compatibility
Getting started involves downloading the companion app and pairing over Bluetooth — a process most smartwatch owners will find familiar. The watch works with both Android and iOS devices, which matters for anyone whose household mixes phone ecosystems, or who switches phones without wanting to switch watches. Because the calling feature depends on Bluetooth staying connected, keeping the app running in the background and your phone's Bluetooth switched on is important for reliable notification delivery and accurate activity logging throughout the day.
Who This Watch Is Built For — and Who Should Look Elsewhere
This is a strong fit if you:
- Want hands-free calling without paying premium-smartwatch prices
- Value being able to change strap colour and watch face to match your style
- Need the fitness-tracking basics — steps, sleep, heart rate, calories — without complexity
- Prioritise multi-day battery life over the sharpest possible screen
- Are buying a first smartwatch, or one for a teenager, parent, or casual user who doesn't need advanced sports metrics
It's probably not the right choice if you:
- Swim regularly and want your watch tracking those sessions
- Train seriously and need clinical-grade GPS accuracy or heart rate precision
- Want an AMOLED display with premium screen quality
- Need fall detection or dedicated safety-monitoring features
- Expect true standalone connectivity without your phone nearby
How It Stacks Up Against Other Budget Calling Smartwatches
The wider market for calling-enabled smartwatches under roughly £50-£70 typically splits along a few axes: screen technology, whether GPS is built into the watch or borrowed from your phone, and how long the battery lasts under regular use. Here's roughly how this watch's specifications position it against the category norms buyers usually encounter at similar or slightly higher price points.
| Category | This Watch | Typical Budget Calling Smartwatch (£40-£70) |
|---|---|---|
| Display type | TFT touchscreen | Often TFT at the low end, AMOLED once you move past £45-£50 |
| Battery life (typical use) | Up to 4 days | Commonly 3-7 days depending on screen type and features |
| GPS | Supported (likely phone-assisted) | Split between phone-assisted and standalone GPS chips, with standalone GPS usually appearing closer to £50+ |
| Strap customisation | Two extra straps included, tool-free swap | Varies widely; interchangeable straps are not universal at this price |
| Water resistance | Splash and dust resistant, not swim-rated | Similar at the low end; swim-rated models generally cost more |
| Starting price point | Around £30 | Often £40-£70 for comparable feature sets |
The clearest advantage here is price relative to feature count — you're getting calling, a full health-tracking suite, and swappable straps for less than most direct competitors charge for a similar spec sheet. The trade-off is the display technology and the likely absence of a truly standalone GPS chip, both of which are common concessions at this end of the market rather than issues unique to this particular watch.
The Honest Trade-offs
The strongest case for this watch is straightforward value: hands-free calling, a genuinely useful set of health metrics, and swappable straps rarely appear together at this price. Setup is simple, the app works across both major phone platforms, and the battery comfortably beats expectations for a device juggling a colour screen and Bluetooth calling. Owners who've bought similar Reflex Active calling watches consistently mention the ease of getting started and general day-to-day comfort as genuine strengths.
The honest weaknesses are just as clear. The TFT display, while functional, lacks the punch of AMOLED alternatives, and the plastic build, while light, doesn't feel premium under close inspection. More importantly, Bluetooth connectivity on watches in this category — including feedback from people who've used this and similar Reflex Active models — occasionally proves inconsistent, with syncing or reconnection hiccups being the most commonly reported frustration. Step and activity accuracy can also drift from what more expensive, sensor-dense watches deliver; treat the numbers as a helpful trend rather than a precise measurement. And because the watch depends on your phone being nearby for calls, notifications, and likely GPS, it's fundamentally a companion device rather than an independent one.
None of this is unusual for the price bracket — it's simply the reality of what £30 buys versus what £150 buys in the smartwatch world. The question is whether the calling feature and the fitness basics matter enough to you that the display and connectivity compromises feel acceptable in exchange.
Final Verdict: Should You Buy It
If your priority is affordable hands-free calling paired with genuinely useful fitness and sleep tracking, and you're comfortable with a TFT display and a plastic build rather than premium materials, this watch delivers real value that's hard to match at its price point. It suits first-time smartwatch buyers, casual fitness trackers, teenagers, parents wanting a lightweight everyday companion, or anyone who simply wants to answer calls without reaching for their phone, without spending £100-plus to get there.
Buy it for what it is: a capable, comfortable, multi-day-battery calling watch at a genuinely low price — not for swimming, elite training accuracy, or a premium look and feel. Within that frame, it's a sound purchase; outside it, you'll want to look toward pricier alternatives that specialise in the areas where this one compromises.
What People Say
60 commentsPerfect watch to match all looks
To start with, the hands-free calling feature is a real game changer. It makes receiving and making calls straight from the watch a very convenient undertaking when on the move or simply don’t want to reach for the phone. Also, multitude interchangeable dials means customisation of the watch face, even with my photos, to give it a personalised look and feel. Pretty extensive with the health and wellness features, it tracks steps, heart rate, blood oxygen levels, even sleep patterns. It also offers cycle tracking and several sports modes to cater for different fitness activities. And having all these insights on my wrist keeps motivating me to stay active and mindful of my health. And to top it off, two additional silicone straps have been included as well: one in cream, the other in coral. Swapping them takes no time at all; you can match it to different outfits or moods. Lightweight with a comfortable fit, I can wear it all day long without any discomfort. The battery life is okay; it lasts me around four days during normal usage, and full charge in three hours. Its IP68 water-proof feature gives me another peace of mind as I wouldn't have to worry about damaging it during workouts or when it rains. Overall, this watch has the perfect combination of functionality and looks.
Designer looks for budget pricing
Moderate battery life of around 4-5 days, depending on settings (constant notifications can drain it quicker). Interchangeable straps (3 with watch) are easy to swap out, lots of notches on the flexible silicone strap allow it to fit a multitude of wrist sizes. Connects to phone via bluetooth. Easy to use interface and app with many different features. Step counter seems to be pretty accurate . Several preloaded watch faces and a good selection of others to download. 1P68 water resistant is a good added feature as a lot are not waterproof at this price range. Good at tracking sleep patterns, stress levels, heart rate, etc. Easy to adjust setting to limit what notifications you want/need. Can play music from phone through watch which is good when exercising. Easy to make and receive calls. Vibration notifications is gentle even on higher setting.
Downfalls: loses all settings when becomes disconnected (notifications/tracking/watch face), app needs to be open on phone constantly to keep connection/tracking so can drain phone battery, vibration notification is very gentle so easy to miss a notification for a call.
The straps are stunning!
Firstly it’s really easy to set up it connects quickly to the strap and was fairly straightforward to do! Charging is simple too as the magnetic aspect means it connects simply to the correct part! I love how it comes with additional straps so you can choose which ever one you like without additional expense! Also the colours of the straps are stunning! I like how you can really personalise the watch by changing the face on the screen too and an added bonus you can have a photo if you choose to also! Answering calls is super easy too and the volume of the calls are brilliant as well! Which means you’re able to answer calls even if your hands are too busy to answer the phone! I love that it also has emails on it so you can get important emails straight away! I feel like the more you use the watch such as with work outs or calls, the battery drains faster however it still gives you a good day and a bit meaning it can be charged over night if you’re not using it to monitor sleep! I think this is a brilliant budget watch that does all the big brands do!
good for a budget watch
I brought on 6th Jan was looking for a main smartwatch after my samsung active 1 stop working like to have a main watch and a back up one and my back up watch is a samsung fit 3 and I did not want to spend big was looking at reflex active watch series saw the series 50 at £29.99 and I could insurance it for about 7 pound for 2 years i see a lot of people say battery is rubbish only charged it twice since I had it love you can answer and make calls plus it connects to strava saves me using both .have all my notification on my watch still get 4 to 5 days battery life.see people have a people with the charger never had problem simple just lay it down .main reason I got one was for calls and steps plus you got extra straps with it .it is a good budget smartwatch for price,easy to set up
A bargain, but extremely limited
For the money, this is amazing. Easy to set up and use, and to adapt to your needs. Looks good, too.
However, its limitations might make it unsuitable for some, including me.
The quality of the microphone and speaker are quite poor, but it's a relatively cheap watch.
It allows you to see only the early parts of any notification. If the substance of the notification is, say, 10 words in, you won't see it. And you can't reply.
The GPS is all over the place. I mapped a few activities and the GPS track was wild - it seems to bounce off things and hugely overestimates distances. I also found that when recording a 4 hour bike ride, the watch stopped recording after to 3 hours.
In short, it's an amazing watch but lacks accuracy.
Amazing smartwatch
Beautiful sleek smartwatch that looks amazing with any outfits. I am impressed with the quality of this watch. It is light on my wrist and can be comfortably worn long periods of time. Comes with three different coloured straps, packaged very nicely. Connecting it to my phone took no more than few minutes and it was good to go. It is water resistant and measures heart rate, your daily activity, sleep etc. Being on the move has never felt so easy with this watch - has the ability to answer calls, show emails and notifications. I definitely recommend it.
Smart watch - Less smart app
I purchased this smart and comfortable Reflex Active watch to replace my 3 year old Huawei watch. Price and features they are fairly equal but the reflex app is nowhere close as good as the Huawei one. Fortunately for everyone else Huawei have dropped the app from the app store and you have to go through a dodgy website. The battery life could also be much better - 10 days at least for the Huawei, about 4 days for the Reflex. If Reflex could sort their battery life and app out, this would be a 5/5 purchase.
Stylish, Practical, and Budget-Friendly Smartwatch
Its calling feature works smoothly, making it convenient to answer calls directly from your wrist. The interchangeable straps add a nice touch of customization, letting you match the watch to different outfits or occasions. Fitness tracking features like step counting and heart rate monitoring are reliable for daily use, and the display is bright and easy to read. Overall, it’s a great option for users looking for a practical smartwatch with essential features and a modern look without spending too much.
Smart Watch
I love the colours of the straps and the fact that you get 3 is even better to colour coordinate with different outfits. The watch itself is really good . It syncs well with the app and is easy to set up !
The watch looks stylish and is comfortable.
The display is quite big dependant on which display you choose.
I would say the only reason I have given it a 4/5 is the battery last approx about 1-1.5 days. However I will say I do have a lot of messages and emails and this will drain a battery more .
Great price for a great product
Recently starting using this watch. The packaging is excellent given the price of the product. Very well presented. Comes with a choice of watch straps which again is an excellent idea and would make me sway more towards this than any other watch. Set up is extremely easy, download the app and it connects via Bluetooth so easily. Instructions are clear and app is very easy to use. The watch its self has quick reactions when navigating. Zero problems with it and extremely pleased
Great watch for the price
After buying cheaper smart watches which didn't always work, I bought this one from reading reviews and I think it's brilliant.
Easy to set up, I can take calls on my watch and listen to favourite radio stations while I'm out walking. It's good to track my walking every morning and encourages me to set goals which I can easily keep an eye on with lots of detail, such as how far I've walked, calories used, number of steps etc.
I would definitely recommend this watch
stylish and sleek
love this smart watch. battery life around 4 days. adjustable strap i have small wrists and was worried it might be too big however its so flexible itll fit any size. works with bluetooth. love that it comes with 3 straps as it means i can edit it to suit so many outfits. accurate step counter. alot of choices for persnoalisation from the face to the menu. added bonus is thats its 1P68 water resistant and will even track my sleep!
Not as easy to set up as my old smart watch.
Replaced my old Huawei smart watch with this as I had recently replaced my old phone with a Google pixel 10a. Struggles with some of the different functionality as I hadn't realised you need to switch on auto monitoring for certain function like heart rate etc. Eventually got working reasonably well then for no apparent reason it wiped all my historical data. Very frustrating tempted to return this item.
Excellent value for money
I recently purchased this item to replace a monitor which I lost in my travels, the strap broke and unknown to me it fell off my wrist. In the past I have had to repurchase various brands for exactly the same reason, the strap breaking. I feel fairly confident that this monitor will outlast my previous purchases in that I have a spare strap which I got with the item. All in all very happy.
Smart (looking) watch
Nice looking and a nice size.
Not too big a face but big enough to read the details which are clear and nicely spaced out.
App was easy to download and easy to follow.
Instructions in the box are also pretty easy to follow.
We had a couple of tricky alterations to make but it didnt take long to remedy.
Easy and quick to charge.
Great little smart watch for the price - my wife loves it.
Good value
Bought this recently to replace my tired smart watch, does everything it's supposed to, very good battery, use it to measure my walking, steps, heart rate etc, a lot of watch faces to choose from, comes with three straps but have my own also, very happy with it, would recommend this to anyone who likes to monitor their exercises but cannot afford the more expensive ones
Great watch and great value
Great looking watch and does it says. Counts steps and can track exercises and trails for walking and running and download them if you want. Easy set up and lots of watch faces to pick from. I did find that the time was slightly out when it wasn’t connected to phone after I took off charge. But overall I’m really
Impressed and great value for money.
That'll do nicely
I am pleased with my watch but it is taking me a while to get to grips with some of the settings an features. Having said that, it is already doing everything I want from it. It is comfortable to wear and the battery charges very quickly. Initial setup was easy with a good bluetooth connection which has proved to be reliable.
Not impressed
Bought this a couple of weeks ago as well priced & good reviews. Worked well for the first week then started having issues. Spamming notifications from my phone & couldn’t clear them so my watch was constantly vibrating even though my phone had no notifications. Also kept resetting my steps to 0 & kept changing date and time.
Reliable and functional smartwatch
This is a great watch for the price range. The features are pretty good and measurements are fairly accurate. It's not at the Garmin level but if you're just looking to get some basic fitness and tracking then this will suffice. Bonus for the calling/receiving features and notifications.
