What to know before buying

Listing details to confirm

Battery runtime is mode-specific: the listing claims up to 40 hours normally and up to 72 hours in Battery Saver mode. Charging claims also differ between 15 minutes of charge time and up to 15 hours of battery from 15 minutes or less. The stated 455 battery capacity has no unit, and a separate 32 GB RAM entry conflicts with the 32 GB storage listing. Confirm these details and LTE service compatibility for your intended setup.

Who is it for?

A good fit for

Android users wanting a 45 mm smartwatch with LTE, GPS and fitness tracking.
People who value a large round watch format and health metrics such as heart rate, SpO2 and HRV.
Runners or hikers who want GPS tracking and multiple exercise modes on the wrist.

Less suited to

Buyers looking for confirmed long battery endurance across their own usage pattern.
