Stop checking a dying phone at every junction. Read your position, compass heading, altitude and heart rate on a rugged metal watch built for hiking and sport.
Navigation tools you can read at a glance

Navigate with a compass on your wrist
GPS positioning and a N/E/S/W compass bezel let you check heading at a glance without unlocking a phone. The green dashboard puts your location next to weather, steps and heart rate, so one screen covers the decision you are making at the junction.

Read your elevation as you climb
Altitude and barometric pressure sensing show your climb on the trail. The silver bezel version keeps the time, date, GPS and calorie readouts on a minimal face, so the numbers you check most stay easy to find on a steep section.
Built to be worn every day
The matte black metal bezel carries visible screw accents, the crown and side buttons are raised for quick use with gloves on, and the textured silicone strap closes on a silver pin buckle. It looks at home on a trail and in the office.
Pair it and set your bearings
- 1Pair over Bluetooth
Connect the watch to your phone to enable calls and sync. Confirm the display, steps and call function respond before you leave.
- 2Learn the three buttons
Use MENU and SPORT on the side and the rotary crown to move between the compass, altitude and fitness screens. Five minutes at home beats fumbling on a ridge.
- 3Fit it snug and calibrate altitude
Wear the strap snug, just above the wrist bone, so the heart rate sensor keeps contact. Recalibrate the altitude reading when you reach a trailhead or marker with a known elevation.
The day the trail stopped making sense
The Junction Nobody Could Read
The path splits, the markers are faded, and your phone is down to a few percent in a pocket. Every stop means digging for it, unlocking it and waiting for a map to load while the light goes. The uncertainty is what wears you down, more than the climb.
Everything You Need, On Your Wrist
The TG02 puts GPS positioning and a compass on the round display, with N/E/S/W markings on the bezel. Altitude and barometric pressure sit on the same face, so the reading you need is one glance away. The phone can stay in the pack.
The Trail Ahead, Clear Again
Heart rate, steps and calories run in the background, and calls come through the watch when you need them. The next trip is easier to plan because you know your heading, your climb and your effort from the start of the route to the last switchback.

Questions and answers
GPS positioning and altitude sensing handle the core job on open trails. Altitude comes from barometric pressure, so it drifts when the weather moves. Recalibrate at a trailhead or marker with a known elevation, and carry a paper map for deep canyons or heavy tree cover.
Yes. GPS, compass and altitude run on the watch itself. The phone is only needed for pairing, calls and syncing data.
Yes. The compass screen shows your heading on the round display, and the N/E/S/W markings on the bezel give you a fixed reference at a glance.
It is a rugged sports watch with a solid metal bezel, so it reads bigger than a slim fitness band. Wear it snug above the wrist bone for sport. If you want a slim dress watch, this is not the one.
The sensor reads from the wrist, so a snug fit matters. For steady trail runs and hikes it gives a useful everyday read. For structured intervals or precise training zones, a chest strap is the stricter reference.
Yes, as long as the watch is paired over Bluetooth and within range. You answer from the wrist and leave the phone where it is.
