At 35mm, this sits closer to a traditional watch diameter than most smartwatches, which tend to run larger, and the black steel bracelet gives it a coherence that rubber-strapped alternatives rarely manage. The always-on AMOLED display means the time is readable at a glance without a gesture, and the range of interchangeable dials — including the option to use your own photograph — means the face can be changed to suit the occasion rather than the watch dictating the look. The practical credentials are substantial for something this unobtrusive: call handling and message notifications direct from the wrist, dual-time for travel, GPS, heart rate and blood oxygen monitoring, sleep and cycle tracking, and a battery that runs up to ten days between charges, with a full charge taking three hours.

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.
