Third-party reviews

What we like about Kospet Tank M3 Ultra

  • The 1.96 inch screen is large and easy to read in direct sunlight.
  • GPS tracking is accurate and rated well in tests.
  • Battery lasts a week to ten days with normal use.
  • Physical buttons work with wet or sweaty hands.
  • Compass and barometric altimeter help on hikes.
  • Rated 5 ATM and IP69K, so it handles swimming and washing.

What we don't like about Kospet Tank M3 Ultra

  • The 56 mm height makes it large on a small wrist.
  • Always-on display cuts the battery to two or three days.
  • Notifications do not arrive from every app.
  • Automatic sport detection covers only a few sports, so others must be picked by hand.
  • No NFC means no contactless payment.

Verdict

Those who want a metal watch with a large, easy screen should look at the Kospet Tank M3 Ultra. The 1.96 inch display is big, and the metal case feels solid. In direct sunlight the screen is close to an Apple Watch. Tracking is accurate, and the GPS run is rated at 42 h. The physical buttons still work with wet or sweaty hands. The battery is rated for 14 days, and tests show about a week to ten days of normal use. The trade-off is size and battery: the case is sizeable, and the always-on screen can cut the battery to a few days. It suits a hiker or outdoor runner who wants a sturdy watch with a big, bright screen. It is rated 5 ATM so a swim is no problem.
