How to use

Charge the smartwatch with the included wireless charger until fully charged (about 2 hours). Pair the watch with your phone via Bluetooth 5.3 and install the Colmi Fit app to configure user profile and enable notifications. Wear the watch on the wrist for continuous health and activity tracking; ensure the HR sensor sits firmly against the skin for accurate measurements. Use the digital crown to navigate menus and the touch display for direct control. Use the phone call function via Bluetooth to make and receive calls through the watch’s built‑in speaker and microphone.

Recommendations

For accurate health data, wear the smartwatch snugly and update firmware via OTA when updates are available. The watch is splashproof (1ATM) but should not be used for scuba diving or high‑pressure water activities. Use the Colmi Fit app for detailed activity history, settings and watch face management.
