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.
Si votre mode de vie vous emmène au-delà du quotidien — que ce soit une course matinale, une baignade ou un week‑end au bord de la mer — votre montre doit pouvoir vous suivre. Chez Nordgreen, plusieurs de nos garde‑temps sont conçus pour allier fonction et esthétique, offrant une étanchéité fiable sans compromettre le design.
Les collections Pioneer et Succession offrent toutes deux une étanchéité 10 ATM, ce qui les rend adaptées à la natation, au snorkeling léger ou simplement aux journées où la vie est un peu plus humide que prévu.
Le chronographe Pioneer incarne l'ingénierie scandinave moderne, où précision et endurance se marient à un style discret. De son côté, la collection Succession adopte une approche plus épurée et minimaliste — une pièce polyvalente qui passe sans effort de la journée de travail à l'aventure.
Chaque montre reflète la conviction de Nordgreen que la praticité doit toujours rester élégante — car le vrai luxe, c'est de ne pas hésiter avant de se jeter dans la vie.
