A live price tracker, not a review — we check UK retailer prices for smartwatches and rank them cheapest first. Right now the lowest is the Apple Watch SE 2nd Gen 40mm from £65 (used). Across the 10 smartwatches we hold a live price on, prices run from £65 to £749 across 3 UK retailers, in new, refurbished and used condition.
Smartwatches are tied to phone ecosystems. The Apple Watch only pairs with an iPhone; Samsung’s Galaxy Watch works best with Android and is fullest on Samsung phones; Garmin and Fitbit work across both iPhone and Android and lead on multi-day battery and sports tracking. Decide based on your phone, then on whether you want everyday smart features or serious fitness and health tracking.
Case size and whether the watch has cellular/LTE (versus GPS only) are the main price levers. GPS-only models are cheaper and pair to your phone for notifications.
Smartwatch batteries degrade with charge cycles, so on used units it is worth checking the grade and battery condition. Refurbished options are tested and sit between new and used.

No — fit it to your phone first. Apple Watch needs an iPhone; Samsung Galaxy Watch is built for Android and fullest on Samsung phones; Garmin and Fitbit are cross-platform. Buying the wrong pairing is the most common smartwatch mistake.
GPS-only models are cheaper and lean on your phone for notifications and data. Cellular/LTE lets the watch call and stream without your phone nearby but costs more up front and usually needs a paid plan — worth it mainly for runners and swimmers who leave the phone behind.
We track 10 smartwatches and currently hold a verified live price on 10 of them across 3 retailers. We only headline a price we can verify, so a model without a trusted live price is listed without one rather than shown a guess.
