Notes on Water-Resistance
Below is The SKMEI general advice on the topic of watch water-resistance:

If your watch is not marked as water-resistant, never get it wet under any circumstances.

If your watch is rated to 50 meters/5bar or less, it should only be subject to accidental splash; hand washing, dishes, etc. Never submerge it intentionally.

If your watch is rated to 100 meters/10bar, it is suitable for surface swimming.

If your watch is rated 200 meters/20bar, it is suitable for skin diving.

If your watch is rated 300 meters/30bar or more, it is suitable for professional and/ or SCUBA diving.

A watch’s stated water-resistance rating is not permanent. Water & debris are kept out of watches by gaskets, and these gaskets can be expected to naturally deteriorate over time. As part of a service, or any time you have a quartz watch’s battery replaced, these sealing components should be thoroughly tested and replaced as appropriate and when possible. If you are planning to swim or dive with a watch, you should always have its water-resistance tested prior to submerging it. Make sure you bring your watch to a professional watchmaker that has the proper equipment to dry-test your watch for water-resistance and replace sealing components as needed. You should never wear a watch, no matter the rating, in warm or chemically treated water, such as in a hot tub, as both temperature and irritants can damage sealing components and/or compromise water-resistance.
