What fog under the glass means, how urgent it is, and the immediate steps to take. Educational emergency guidance only.
Do:
• Remove the watch from water immediately
• Keep it dry on the outside
• Note whether fog clears or worsens
• Arrange service quickly if moisture persists
Don’t:
• Do not use a hairdryer on high heat
• Do not open the case yourself unless trained
• Do not keep swimming with it
• Do not ignore droplets inside the crystal
Temporary external-temperature fog against the crystal can sometimes clear. True internal moisture is a service issue.
Is fog inside a watch dangerous?Persistent internal moisture is serious because it can corrode the movement and stain the dial.
Why did my watch fog after a shower?Steam and weakened gaskets/crown sealing are common reasons.
Can I dry it with rice?Do not rely on rice. Professional drying and gasket service are the real fix path.
Will it still be water resistant after this?Assume no until pressure-tested after proper service.
