Advanced Sports GPS Waterproof Fitness Tracker Smartwatch

The Advanced Sports GPS Waterproof Fitness Tracker Smartwatch from Northstar is built for training and outdoor use. It has a round 1.75-inch AMOLED touchscreen at 466 x 466 resolution, covered by a sapphire crystal lens, set in an alloy case with a detachable silica gel band. The band measures 260mm long and 22mm wide.

It runs more than 120 sport modes and uses multi-satellite GPS with a compass and barometric sensor for outdoor navigation. Health tracking covers heart rate, blood pressure, blood oxygen, sleep, stress and women's health metrics. You can make and take Bluetooth calls from the wrist, and the watch is water resistant to 50 meters, so it handles swimming. The 1000mAh battery lasts up to 10 days depending on how heavily you use GPS, calling and the screen.

It pairs with Android and iOS phones through the Da Fit app and offers over 200 cloud watch faces. Band and finish options include Black, Orange, Black Steel and a Black Mesh Belt. Two things worth knowing before you buy: the health readings are for fitness and wellness, not medical diagnosis, and the listing only names the watch itself in the box, with no charger or cable specified.
