What to Do If Your Watch Gets Water Damage

If you see fog or droplets under the crystal, act quickly: take the watch off, do not operate the crown or pushers, keep it somewhere warm, and get it to a watchmaker to be opened and dried as soon as you can. Water inside a watch means a seal has failed, and the clock is now running on corrosion. Speed matters more than anything else you can do.

• See condensation: stop wearing it immediately.
• Do not: pull the crown, press pushers, or try to run it warm on a radiator.
• Do: get it opened, dried and inspected by a professional, fast.
• Why the rush: steel components rust within days, not weeks.

Why moisture inside is serious

A watch keeps water out with gaskets at the caseback, crystal and crown. When one hardens, tears or was left open, water gets past it, and it does not evaporate the way a puddle does. It sits against tiny steel parts, the pivots, the springs, the screws, and begins to rust them. Left alone, a movement that could have been dried and re-sealed cheaply turns into a corroded mess that needs parts. The difference between a small bill and a large one is usually how fast you reacted.

The first few minutes

1. Take it off and dry the outside. Wipe the case and crystal with a soft cloth so no more water works its way in.
2. Leave the crown alone. Pulling the crown opens the very channel you are trying to seal. Do not set the time, do not wind it, do not touch the chronograph pushers.
3. Keep it gently warm, not hot. Room temperature or a warm pocket is fine. Never a radiator, oven, hairdryer or direct sun; heat expands the moisture and can warp gaskets and damage the dial.
4. Get it to a watchmaker. This is the real fix. The case has to be opened, dried properly and inspected, then resealed and pressure-tested.

What not to try at home

The internet is full of confident bad advice on this.

• Rice. It does very little for a sealed case and leaves dust and starch behind. It will not reach the moisture that matters.
• Heat. Radiators and hairdryers push moisture deeper, cook the lubricants and can crack a crystal or lift the dial. Avoid entirely.
• Freezing. A myth. It does nothing useful and risks thermal shock.
• Running it to "dry it out". Every second the movement turns in a wet case, it wears and corrodes.

How the water got in

Usually one of a handful of things. A crown left unscrewed before a swim. Aged gaskets that were never replaced. A crown or pusher operated underwater. Or a watch pushed past its rating, a 30m dress watch taken swimming, say. Understanding the rating prevents the repeat, and it is laid out in our water resistance ratings guide. The short version: those numbers are static lab pressures, not depths, and they degrade with age.

After it is dried and fixed

A watch that has taken on water should be pressure-tested and have its gaskets replaced before it goes near water again. Water resistance is not permanent; it relies on rubber seals that harden over the years, which is why divers and daily swimmers should have the seals checked periodically. If the crown is a screw-down type, get in the habit of seating it fully every time, covered in our screw-down vs push-pull crown guide. General upkeep is in cleaning your watch at home.

If a watch is beyond economical repair, a reliable modern piece with a fresh, tested seal is the safer long-term answer. The dive watch collection and the wider shop carry watches pressure-tested before they ship.

Do this, not that

• Do: remove it, keep the crown shut, keep it mildly warm, see a watchmaker within days.
• Don't: apply heat, use rice, freeze it, or keep wearing it.
• Do: have the seals replaced and pressure-tested afterwards.
• Don't: assume it is fine because the fog cleared. The moisture is still inside.
