Smart Watch 1.27 AMOLED Fitness Watch with Heart Rate, Sleep & Stress Monitoring, 3ATM Waterproof (w/voucher at checkout) Tensky / FBA

Looks like a decent all-round fitness watch if you want the usual tracking features without going for one of the bigger-name models.
It has a 1.27 AMOLED display and tracks heart rate, sleep and stress, along with 120 sports modes for different activities.
Its also rated 3ATM water resistant, so it should be fine for everyday use and workouts where it might get wet.
