Go Farther. It Knows the Way Back.
Zenith Pro is an AMOLED GPS smartwatch carrying the instruments your phone does not have. Multi-satellite GPS with route back-tracking, compass, altimeter and barometer — plus heart rate, blood pressure and blood oxygen, a ChatGPT voice assistant and Bluetooth calls, all in a rugged three-proof body with a 1.56-inch AMOLED.
✓ Free shipping ✓ 30-day money-back guarantee ✓ Works with iPhone & Android
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.
The same watch that back-tracks your route also keeps female cycle reminders on board — predictions and gentle nudges in the same app as your heart rate, blood pressure and sleep. Adventure watch by build, health watch by habit, for everyone on the trail.

“The back-track feature paid for the watch on day two — fog rolled in and it walked me straight back to the trailhead.”
“Compass and altimeter on the wrist means the phone stays dry in the pack. Exactly what I wanted.”
“Asked the ChatGPT assistant to settle a campfire argument. It did. The heart-rate alerts are the quiet hero though.”

Screen technology and satellite coverage pull in opposite directions on battery. Here is how the trade works, and what each part genuinely buys you.
AMOLED lights individual pixels rather than a whole backlight, which is what allows deep contrast and a display readable in sunlight without burning power on a mostly-black watch face. That efficiency is precisely what makes an always-on face survivable on a watch that also records GPS.
GPS is one system; adding BDS, GLONASS, Galileo and QZSS means more satellites visible when half the sky is blocked by valley walls or forest canopy. The official US government page on GPS accuracy explains what to realistically expect. More in our multi-satellite guide.
The watch records where you walked and can lead you back along the same line. It is not turn-by-turn navigation and it does not know about paths you did not take — it retraces your own track. That is genuinely useful in fog or failing light, and it is not a substitute for a map and compass you know how to use.
A magnetic compass and a barometric altimeter need no phone, no signal and no satellites. Hold the watch level and away from metal for the compass, and calibrate altitude at a known elevation — the National Weather Service explains what pressure changes signal. See our altimeter guide.
Voice assistance runs through your paired phone and its data connection, so it stops at the edge of coverage — exactly where the compass and altimeter carry on. Useful in town, irrelevant on the mountain. More in what a watch assistant can actually do, and read the National Park Service hiking safety guidance before relying on any of it.

AMOLED lights each pixel individually, so blacks are genuinely off rather than dimly lit. That gives much better contrast in direct sunlight and uses less power on a dark watch face, which is what makes an always-on display practical alongside GPS recording. The trade is cost, and that very bright content drains more than an LCD would — a mostly-black face is the efficient way to run one.
Yes. The watch records your track from the satellites directly and retraces that same line, all offline. What it cannot do is route you along a path you have not walked, or recalculate around an obstacle, because it is following your own recorded track rather than a map. Treat it as breadcrumbs, and carry a map for anything else.
Yes — the Zenith Pro works with Android phones and iPhones through its free companion app, with Bluetooth calling and notifications on both.
No. GPS, maps-free back-tracking, the ChatGPT assistant, every sensor and sport mode — all included in the price, permanently.
About 10 hours of continuous GPS tracking on the 650mAh battery, with a power-management system that stretches everyday use much further between charges.
No. The trajectory-return and round-trip route planning run on the watch itself, using its own multi-satellite positioning — your phone can stay in the pack.
The Zenith Pro is built three-proof — rain, sweat, splashes and dust are fine. It isn’t built for swimming or showering.
Wear it for a full month of trails. If it hasn’t earned its place, our 30-day money-back guarantee refunds you in full — no restocking fee, no fuss.
