Your outdoor day gets tracked and protected, so the watch stops being the thing you worry about. A rugged octagonal case, 3ATM water resistance and a drop-proof build cover the pool, the trail and the job site. Heart rate, blood oxygen, blood pressure and sleep keep running in the background.
Rugged smartwatch built for outdoor sports with 3ATM waterproofing and health tracking
- water exposure during swimming and outdoor activity
- tracking health metrics on the go
- durability in harsh outdoor conditions
Wear the tough watch your outdoor days demand
Before: a delicate watch you leave at home when the weather turns. After: a rugged, waterproof companion that tracks your heart rate through the trail, the pool and the job site.
Rugged Design That Works Outdoors

Built to take the knocks
The octagonal case has a dark bezel and a rubber strap that feel made for field work. It is drop-proof up to 1.5m and fully dust-proof, so a knock on a tailgate or a day in the dirt is nothing to fuss over.

Ready for the water
3ATM water resistance covers submersion down to 30m. Take it swimming, out on open water or onto a wet boat deck. Keep it out of baths, showers and saunas, since heat and steam fall outside what the rating covers.

Heart rate, all day
The heart rate sensor sits on the case back and runs through the day. The newer HRS3603 sensor uses less power, and the watch also tracks blood oxygen, blood pressure and sleep.

The watch you left at home

The watch you left at home
You know the feeling. The trail looks good, the forecast is shaky, and the watch stays in the drawer. Slim smartwatches crack, fog and die in rain, pool water and dust, so most active men end up with a fitness band they barely trust, or no tracking at all.

Built for the conditions
A rugged octagonal case changes the math. The watch is rated 3ATM for water, drop-proof up to 1.5m and dust-proof. The dark bezel and rubber strap look picked for work, not for a display case, and the army green finish fits a field kit without trying too hard.

Wear it through the whole day
Swim in the morning, hike the ridge at noon, finish a shift in the afternoon. The heart rate sensor keeps reading in the background, so the data from each session is still there when you check it that night.
Keep It in Top Shape
- No baths, showers or saunas
Heat and steam fall outside the water rating, so take it off first.
- Rinse after salt water or chlorine
A quick rinse with fresh water after a swim keeps the strap and bezel clean.
- Store within the temperature range
High temperature storage is rated up to 55°, so keep it out of a hot car.

Questions and answers
3ATM is rated for submersion up to 30m, which covers swimming, pool laps and open-water sessions. The rating is a static pressure figure, so check your sport against it before diving. Keep it away from hot water and steam in every case.
It tracks blood pressure along with heart rate, blood oxygen and sleep. Treat the readings as trends to follow over time, not as a medical diagnosis.
No. Take it off before a bath, shower or sauna. The water rating covers submersion, not hot water or steam.
A slim band is cheap until it cracks on the first rock or dies in the first downpour. This watch has an octagonal rugged case, 1.5m drop-proofing and a dust-proof build, so you wear it on the hard days instead of replacing it each season.
The case is plastic, but it is built like a work tool: rugged octagonal shape, dark bezel, rubber strap, dust-proof and drop-proof up to 1.5m. You pay for that toughness and for the military-inspired finish, not for a metal shell that you would scratch anyway.
