Reflex Active RA53-2230-SET Nexus 100 Smartwatch With Interchangeable Straps - W47363
Ref. RA53-2230-SET
A compact 42 × 25mm rectangular case keeps this firmly in the smaller-wrist category, and at 40 grams it is light enough to wear through the night for sleep tracking without noticing it is there. The set includes both grey and black silicone straps, which swap out on the 16mm lugs — a small practical detail that means the watch reads differently on different days without buying anything further. The 1.45-inch touchscreen supports fully customisable watch faces, including the option to use a personal photograph as the dial, and full smartphone notifications arrive over Bluetooth alongside music and camera remote controls. Health tracking covers the expected ground — steps, calories, heart rate, blood oxygen and cycle tracking — plus GPS for mapping outdoor activity without carrying a phone.

Learn more about Reflex Active
Reflex Active is a British brand launched to put smartwatch features at a price a parent would consider for a teenager, and it has stayed at that end of the market deliberately.
The proposition is straightforward: heart-rate and activity tracking, notifications, sleep monitoring and interchangeable coloured straps, in bright cases with animated watch faces, generally for under a hundred pounds.
That places it against fitness bands rather than against watchmaking, and the comparison it invites is with devices costing several times as much. Battery life and app polish are where the price shows; the core tracking does what it claims.
The range is broad and changes quickly, with series numbers denoting feature sets rather than model families, and gift sets pairing a watch with spare straps.
It is a first smartwatch rather than a watch in the traditional sense, and it is priced and designed with exactly that buyer in mind.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 68m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Will the glass scratch?
It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.
Is it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
