Everything below is verified against the manufacturer spec sheet — trail-tested features, no vapour.
GPS, Beidou, GLONASS and Galileo with multi-frequency L1+L5 positioning for fast, accurate fixes.
Wander freely — the trajectory-return feature guides you back along your own track.
Real outdoor instruments: direction, altitude and air pressure at a glance.
A fifth-generation optical sensor tracks heart rate all day, plus blood pressure and SpO₂.
Ask the built-in ChatGPT assistant anything mid-trail; AI watch faces included.
Bluetooth calling, 100+ sport modes and a rugged three-proof build with 650mAh battery.
Zenith Pro fixes your position with GPS, Beidou, GLONASS and Galileo — using multi-frequency L1 and L5 signals so the blue dot stays honest in canyons, forests and city blocks alike.
Pick a distance and explore. If you stray, dynamic round-trip route planning redraws the path from wherever you are — and trajectory return walks you back along your own footsteps.
For wellness tracking and awareness — not a replacement for professional medical advice.
A real compass with two calibration methods, live altitude and air-pressure readouts — the practical outdoor toolkit that keeps a bad-weather day from becoming a bad decision.
Designed for awareness and conversation with your physician — not for diagnosis.
The fifth-generation optical sensor watches your heart rate around the clock, with blood pressure and blood-oxygen checks on demand — because summit day depends on the machine under the jacket.
Hands full of trekking poles? Speak. The built-in ChatGPT assistant answers questions, the AI dial generates fresh watch faces, and Bluetooth calling keeps base camp in reach.
Scientific sleep tracking meets health big data: nights are staged and scored, sedentary hours get a nudge, and cycle reminders keep the whole picture in view.
