What the Ex108 smartwatch does

The allentian Ex108 is a round-dial wearable with a 28mm case built from aluminium alloy and a silicone strap. It pairs with Android and iOS phones to show calls, messages and app alerts on a TFT touchscreen. Health sensors track steps, heart rate, blood oxygen, blood pressure and sleep stages. Wireless charging keeps the battery going for seven days or less.

Battery life in daily use

A full wireless charge supports up to seven days of typical wear including notifications, occasional Bluetooth calls and continuous heart-rate sampling. Heavier calling or always-on display settings will shorten that window, so users who want multi-day freedom without a nightly top-up should expect to charge roughly once a week.

Water resistance limit

The Ex108 carries a life-waterproof rating that handles rain, hand-washing and sweat during workouts. It is not rated for swimming, showering or submersion, so buyers who need a watch for pool laps or water sports should look elsewhere.
