Waterproof Smartwatch with 24H Heart Rate & 14-Day Battery

A rugged watch that keeps up with your workouts

Heart rate, all day long

The sensor sits on the back of the case and reads your pulse across the whole day, not just during a workout. The on-screen graph shows the full 24-hour curve, and the live bpm readout, such as 88 bpm, lets you check effort mid-run without reaching for your phone. Blood pressure and blood oxygen are tracked as wrist-based estimates for trends.

Built for rain and pools

The octagonal case and IP67 rating handle rain, sweat and splashes, and the watch is listed for swimming. Rinse it with fresh water after a pool or sea session to keep the strap and buckle clean.

Charge it once a week

Packaging lists up to 6 days of typical use and 14 days on standby. The battery indicator shows the level at a glance, and the magnetic charging contacts on the back make topping up take seconds before you head out.

From a dead watch to a full week of data

The watch that quit midweek

Wednesday is the day the watch dies. You charged it Sunday night, wore it through two runs and a gym session, and now the screen is blank before the weekend race. A watch that cannot last the week gets left in a drawer, and the first hard rain usually finishes it off.

Why all-day heart data matters

A single workout tells you how hard you pushed. It does not tell you how your heart handled the rest of the day. The COLMI P10 monitors heart rate around the clock and draws a 24-hour chart on the color screen, so you can see your resting baseline, the spikes after a hard session and the quiet stretches in between.

One watch for every session

The COLMI P10 has a rugged octagonal case, a full-touch display and multi-sport modes for running, cycling, gym work, swimming and yoga. Wear it from the gym to the trail to the pool without swapping devices. Charge it about once a week and it stays on your wrist for the whole training block.
