Who this watch fits

The ZOSKVEE Tk21p ECG smart watch in brown leather targets women, men, couples, adults and the elderly who want a round-dial wearable with an IP screen running at 360*360 resolution and a 280 mAh battery rated for 7-14 days of use.

Daily comfort and power

An aluminium-alloy case and silicone wristband keep the weight at 50 g, while wireless charging and life-waterproof sealing let the touch-button interface run heart-rate, blood-oxygen, body-temperature and sleep tracking without frequent top-ups.

Sustained health tracking

Continuous monitoring of steps, blood pressure and oxygen saturation stays active through multi-sport sessions and overnight sleep cycles, and the 7-14 day endurance means the sensors keep logging data across weeks rather than single workouts.

Highlights

  • ECG monitoring for heart health insight
  • 7-14 day battery life between charges
  • Blood oxygen and temperature tracking included
  • Lightweight 50 g design suits all-day wear
  • Water-resistant build handles daily splashes

Questions about this item

How do I start using the Tk21p and which step is often missed?

Charge the 280 mAh battery fully via wireless charging, then pair the watch to the iOS device through the companion app; the step most users skip is granting all health-sensor permissions in the app before the first measurement.

What will need replacement on the Tk21p over time?

The silicone wristband and the wireless charging line are the only parts that wear out; the 50 g aluminum-alloy case and IP-rated seals are not user-serviceable.

What limits continuous ECG or SpO₂ tracking on the Tk21p?

The 280 mAh cell delivers 7 to 14 days in normal use, but sustained ECG or blood-oxygen sessions drain it in roughly one day, so battery life is the first constraint.
