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.
Hvis din livsstil tager dig ud over det daglige — hvad enten det er en morgentur, en svømmetur eller en weekend ved kysten — bør dit ur kunne følge med. Hos Nordgreen er flere af vores tidstagere designet til at balancere funktion og form, og tilbyder pålidelig vandtæthed uden at gå på kompromis med designet.
Både Pioneer og Succession kollektionerne har 10 ATM vandtæthed, hvilket betyder, at de er klar til svømning, let snorkling eller de dage, hvor livet bliver en smule vådere end planlagt.
Pioneer-kronografen indkapsler moderne skandinavisk ingeniørkunst, hvor præcision og holdbarhed møder underspillet stil. I mellemtiden byder Succession-kollektionen på en strammere, mere minimalistisk tilgang — et alsidigt ur, der går ubesværet fra arbejdsdag til eventyr.
Hvert ur afspejler Nordgreens tro på, at praktisk funktion altid skal føles elegant — for ægte luksus er, når du ikke behøver at tænke dig om før du kaster dig ud i livet.
