All-day health monitoring

The H20 Ultra smart watch tracks steps, heart rate, blood pressure and sleep patterns to give a daily picture of your wellbeing. It also counts steps and monitors activity across ten built-in sport modes. The 180G case sits on a silicone sport strap for comfortable continuous wear. Touch and button controls keep navigation simple during workouts or daily tasks.

Week-long battery with wireless charging

A single charge lasts up to seven days under normal use, reducing the need for frequent top-ups. Wireless charging removes cable clutter and makes overnight replenishment straightforward. The life-waterproof rating handles sweat, rain and hand-washing without worry. Plastic construction keeps the device light while maintaining durability for everyday conditions.

Calls and alerts from your wrist

Bluetooth calling lets you answer or dial directly from the watch when your phone is within ten metres. Intelligent reminders push notifications for messages, calendar events and social apps without reaching for your handset. A remote selfie trigger captures group shots or solo portraits from a distance. Voice assistant access adds hands-free convenience for queries or smart-home control.
