Dive Watch Buying Guide: What 200M Water Resistance Really Means
You're shopping for a watch and see '200M water resistance' stamped on the case back. Does that mean you can dive 200 meters deep? Can you swim with it? Shower? The truth about water resistance ratings is more complicated—and more important—than most people realize. Misunderstanding these ratings can lead to a ruined watch and a hefty repair bill. Let's decode what water resistance really means and help you choose the right watch for your aquatic adventures.

Water Resistance vs. Waterproof: A Critical Distinction

First, a crucial clarification: no watch is truly 'waterproof.' The correct term is 'water resistant,' and there's a big difference. Water resistance describes a watch's ability to resist water intrusion under specific test conditions. It's not a guarantee that water will never enter the case—it's a statement about the watch's tested limits. The term 'waterproof' implies absolute protection, which is impossible. Gaskets degrade over time. Crowns get damaged. Temperature changes affect seals. Even the best dive watch can leak if it's not maintained properly. This is why watch manufacturers and regulatory bodies mandate the use of 'water resistant' rather than 'waterproof.' It's not just semantics—it's about setting realistic expectations.

Conclusion

Understanding water resistance ratings is essential for choosing the right watch and protecting your investment. Remember: ratings indicate tested limits, not guarantees. A 200M dive watch is your safest bet for swimming, snorkeling, and recreational diving. Maintain your watch's water resistance with regular pressure testing and gasket replacement. And when in doubt, take the watch off—no timepiece is worth the risk of drowning or injury. Ready to find your perfect dive watch?
