This is a minimalist offering, with a round, customisable watch face and a choice of six different straps, to suit your style. It features a fitness tracker, which monitors steps, distance travelled and calories burned across a range of activities, as well as sleep patterns. When synced to an iOS, Android or Windows Phone smart device, it allows users to set goals, monitor progress and analyse performance. The full-colour ZeCircle2 provides smart notifications about incoming calls and text. The watch also functions as a contactless payment device, with a battery life of 5 days.
