San Martin: If a watch is water-resistant, this will be mentioned on the dial or case back. If no specific depth is mentioned and the watch is labeled as water-resistant, it means it meets general water-resistant standards. However, water resistance does not last forever. The gaskets around the crown, crystal, and case back can wear out over time and should be inspected regularly. This inspection is typically limited to a visual inspection for all water-resistant watches. Typically done during battery replacement, silicone lubrication can help extend the gaskets’ lifespan – SAN MARTIN WATCHES
