A compact smartwatch built around hands-free calling, the Nexus 100 keeps phone conversations on the wrist without requiring the phone to leave a pocket or bag. The 25mm width sits comfortably on a narrower wrist, and the gold PVD case with black dial gives it a warmer, less utilitarian look than most fitness-focused devices at this size. The set includes two silicone straps in contrasting colours, so the watch reads differently depending on which is fitted — a practical way to shift between a casual and a dressed-down look without buying anything separately. Beyond calls, it tracks blood oxygen, sleep, cycles and multiple sports modes, all managed through the companion app.

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. 67m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Water resistance explainedWill the glass scratch?
It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.
Sapphire, mineral and acrylic comparedDoes it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedIs it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
Cheapest place to buy
F.Hinds is the only UK retailer we track stocking this reference, so there is nothing to compare it against today.
