Water Resistance Reminder
Water resistance ratings are a guide only and are based on laboratory testing under controlled conditions. In everyday use, sudden pressure changes, temperature shifts, soaps, impacts, and ageing seals can all affect your watch’s ability to resist water.
| Indication | Sweating | Handwashing, Rain | Shower, Bath, Swimming | Diving, Snorkeling | Deep Diving, Water Sports |
|---|---|---|---|---|---|
| Not Waterproof | NO | NO | NO | NO | NO |
| 3 ATM (30 m) | YES | NO | NO | NO | NO |
| 5 ATM (50 m) | YES | YES | NO | NO | NO |
| 10 ATM (100 m) | YES | YES | YES | NO | NO |
| 20 ATM (200 m) | YES | YES | YES | YES | NO |
| + 30 ATM (300 m) | YES | YES | YES | YES | YES |
Important Notes
Water resistance is not permanent and may reduce over time due to normal wear, ageing gaskets, accidental knocks, or exposure to chemicals such as soap, perfume, sunscreen, and cleaning products.
Hot water and steam can still affect seals over time, so extra care is always recommended even on higher-rated watches.
Always ensure the crown is fully pushed in, and if applicable, screwed down before any contact with water.
