San Martin: A watch’s dial or case back will indicate whether it is water resistant. The watch meets general water-resistant standards if no specific depth is mentioned and it is marked as water-resistant. However, water resistance is not a permanent feature. Regular inspection is recommended for the crown, crystal, and case back gaskets because they can degrade over time. For a general water-resistant watch, this inspection is often just a visual check. Typically done during battery replacement, silicone lubrication can help extend the gaskets’ lifespan – SAN MARTIN WATCHES
