Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
All six listings state a warranty term and a battery figure, but the battery figures are each brand's own and are given for different modes, from normal use to smartwatch mode. The Garmin and Samsung listings give no water rating in the features we read; the Garmin listings describe their health data as close estimations of metrics tracked, and the fēnix 7X Pro Solar listing says it is not a medical device.
Our Take
The Fitbit Sense 2 is the default pick: its listing states built-in GPS, on-wrist calls, 50m water resistance, iOS and Android compatibility and a 2 year warranty. Choose the Garmin fēnix 7X Pro Solar for its listed solar charging, multi-band GPS and up to 37 days of battery, or the Samsung Galaxy Fit3 for its listed 1.6" AMOLED display, up to 13 days of battery and 3 year warranty.
