However, it is important to note that water resistance ratings are not guarantees. The following tips can help you protect your water-resistant watch from damage:
1. Do not expose your watch to water depths greater than its water resistance rating.
2. Do not wear your watch while swimming or showering.
3. Do not submerge your watch in water for extended periods of time.
4. If your watch comes into contact with water, rinse it off with clean water and dry it with a soft cloth.
5. If you notice any water inside your watch, have it inspected by a qualified watchmaker.
Pressure Resistance of Common Watch Materials
| Material | Pressure Resistance |
|---|---|
| 316L Stainless Steel | 300M |
| Sapphire Crystal | 1000M |
| Mineral Glass | 50M |
| Rubber | 100M |
| Silicone | 100M |
If you are unsure about the water resistance rating of your watch, it is best to err on the side of caution and avoid exposing it to water. Remember, a little water can go a long way in damaging your watch, so it is important to take care and protect your investment.
