What is “ATM” in a watch context
When you see “3 ATM”, “5 ATM” or “10 ATM” on a watch, it refers to how much water pressure the case can resist. “ATM” stands for atmospheres, a unit of pressure. One atmosphere equals the pressure at about 10 meters of water depth.
That means a 5 ATM watch has been tested to resist pressures equal to 50 meters of water. However, these are laboratory conditions — not real-life diving depths. In reality, movement, splashes, and temperature changes can all increase pressure on the watch, so the actual limits are lower than the numbers suggest.
What each water rating means in real life
To help you translate these numbers into everyday situations, here’s a quick guide:
- 3 ATM (30 meters): Handles daily moisture like hand-washing, light rain, or splashes. Not suitable for swimming or showers.
- 5 ATM (50 meters): Safe for short swims and exposure to water during daily activities, but avoid high-pressure jets or long immersion.
- 10 ATM (100 meters): Great for swimming, snorkeling, and water sports — though still not made for deep diving.
- 20 ATM (200 meters): Built for active water adventures and diving to recreational depths.
- 30 ATM and above: Designed for professional diving and demanding underwater conditions.
It’s also important to remember that water resistance isn’t permanent. Over time, seals and gaskets can wear out, especially if the watch is exposed to soaps, heat, or salt water. Regular maintenance ensures your watch remains as protected as the day you bought it.
A few design details can make a big difference — such as screw-down crowns, sealed case backs, and stainless-steel construction — all of which enhance how well a watch resists water in daily life.
Se il tuo stile di vita ti porta oltre la routine — che sia una corsa mattutina, una nuotata o un weekend in riva al mare — il tuo orologio dovrebbe saperti seguire. Da Nordgreen, diversi dei nostri orologi sono progettati per abbinare quel equilibrio tra function and form , offrendo affidabile resistenza all’acqua senza compromettere il design.
Sia le collezioni Pioneer che Succession presentano una 10 ATM water resistance, il che significa che sono pronte per nuotare, fare snorkeling leggero o semplicemente per quei giorni in cui la vita diventa un po’ più bagnata del previsto.
Il cronografo Pioneer incarna l’modern Scandinavian engineering, dove precisione e resistenza si incontrano in uno stile discreto. Nel frattempo, la collezione Succession propone un approccio sleeker, more minimalist — un pezzo versatile che passa con facilità dalla giornata di lavoro all’avventura.
Ogni orologio riflette la convinzione di Nordgreen che la praticità debba sempre apparire elegante — perché il vero lusso è non doverci pensare due volte prima di tuffarsi nella vita.
