Fog or droplets under the crystal mean moisture has entered the watch. That is not normal, and it should not be treated as a cosmetic issue.
Act quickly
- Take the watch off.
- Keep it away from more water.
- Do not operate the crown or pushers.
- Bring it to a watchmaker as soon as possible.
Water can damage the movement, dial, hands, lume, and electronic parts. Even if the fog disappears, moisture and residue may still be inside.
Skip the rice trick
Rice does not open the case, clean the movement, or replace a failed gasket. A hair dryer can damage lubricants, adhesives, seals, and the dial. Leaving the crown open may also pull dust inside.
What the watchmaker checks
A proper inspection may include drying the case, checking for corrosion, testing the movement, replacing gaskets, and pressure testing after reassembly.
Why condensation happens
- A worn or pinched gasket
- A crown left open
- A cracked crystal
- A poorly sealed case back
- Water exposure beyond the rating
Do not return the watch to water until the cause is fixed. Our water-resistance guide explains what the ratings mean.
