Ever wondered what would happen if Samsung combined the stainless steel style of its smartwatches with software based on Wear OS? Wonder no more: the new Galaxy Watch 4 is the first to run Wear OS 3. Playing nice with Google means a bigger app catalogue, while Samsung’s One UI overlay gives the Watch 4 a slick, icon-based interface which harks back to Tizen. Four variants will hit shelves on 27 August: the streamlined and sporty Watch 4 will ship in 40mm (£249) and 44mm (£309) sizes, while the more traditional Watch 4 Classic – complete with rotating bezel – measures in at 42mm (£349) and 46mm (£369). Dropping an additional £40 bags you 4G eSIM connectivity, but you don’t need to spend an extra penny to access the suite of fitness features. Besides familiar activity modes, a new Body Composition tool analyses body fat, water weight and bone density for a more accurate measure of your lifestyle. Add 40-hour battery life into the mix, plus a new Exynos processor and the promise of streamed TV workouts, and the Apple Watch Series 6 has some serious competition.
