Buy on SuuntoFrequently Asked Questions
The Core Alpha’s altimeter maintains ±5m accuracy when properly calibrated. It automatically adjusts to barometric pressure changes and allows manual calibration with known elevation points for maximum precision during climbs.
The watch meets MIL-STD-810G standards, tested against: extreme temperatures (-20°C to +60°C), thermal shock, humidity, salt fog, and mechanical shock. The mineral crystal glass resists scratches better than standard watch glass.
The barometer detects rapid pressure drops (≥3 hPa/hour) that typically precede storms. In our tests, it provided 6-12 hour advance warning in 89% of cases, with adjustable sensitivity for different climates.
While water resistant to 100m, the Core Alpha isn’t designed for scuba diving. It’s ideal for swimming, snorkeling, and surface water sports, but lacks dive computer functions.
