Product Information
The Suunto Core Alpha Stealth is the no-battery-anxiety, no-nonsense tool watch: a traditional ABC (altimeter, barometer, compass) outdoor watch built to military-grade durability for off-grid use, in a blacked-out stealth finish that stays subdued in the field. There is no GPS to charge and nothing to sync — a user-replaceable CR2032 cell runs it for about 12 months of continuous time mode, and every sensor works with no phone and no signal.
The barometric altimeter tracks ascent and descent from -500 m to 9,000 m, the barometer graphs sea-level pressure and fires a storm alarm when it drops fast, and the digital compass with bearing lock keeps you oriented to 1° resolution. Sunrise/sunset times, dual time, countdown and stopwatch timers, and a 10 m depth meter for river crossings and snorkeling round out the toolset. Water resistant to 30 m, operating from -20°C to +60°C, with a 140-240 mm wrist fit.
- Altimeter, barometer, and digital compass — fully self-contained, no GPS or phone needed

- Storm alarm triggered by rapid barometric pressure drop
- Barometric altitude from -500 m to 9,000 m with ascent/descent totals
