Useful information: What makes a watch water-resistant?
There are several features that help make a watch water-resistant. The most important is the gaskets, or 0 rings-made of rubber, nylon or Teflon which form watertight seals at the joints where the crystal, case back and crown meet the watch case. if the watch is a chronograph, the chronograph pushers will also have gaskets.
In addition, water-resistant watch cases are lined with a sealant, applied in the form of a quick-hardening liquid, which helps keep water out. |
