Overview
Answering and making calls from the wrist, this Tensky watch pairs with a phone over Bluetooth and shows notifications on a square LCD. An aluminum case holds the screen, and a silicone band closes with a tang buckle.
A big screen, voice assistant and health sensors cover calls, workouts and sleep tracking. Positioning comes from the paired phone, and any cellular use is undocumented.
Who it's for
A casual fitness user who wants to take calls, track sleep and run workouts with the phone nearby. Anyone expecting independent GPS or a working cellular line should look elsewhere.
Pros and cons
- Alexa voice control
- Water resistance for swimming
- Wide range of sport modes
- GPS depends on the phone
- Cellular entries are unexplained
- Battery capacity listed two ways
- Little onboard memory
Performance notes
Calls and notifications work while the phone stays in Bluetooth range, and the phone also supplies location. Heart rate, sleep and blood oxygen readings come from the wrist sensors and are wellness estimates. Battery runtime drops with screen use and frequent calls.
