f you suspect your Rolex is not waterproof or has already taken on moisture, the most crucial step is to act immediately to prevent long-term damage like rust or corroded components.
Immediate Emergency Actions
- Stop the watch: If it is a manual-wind, do not wind it. If automatic, do not shake it. Keep it upright with the crown facing down.
- Pull the crown: Pull the crown out to the furthest position to allow air into the case.
- Dry the exterior: Gently blot the watch with a clean, dry microfiber cloth.
- Try desiccant packets: Place the watch in a sealed container or bag with silica gel packets to help absorb internal moisture.
- Avoid heat: Do not use a hairdryer, oven, or direct intense sunlight to dry it, as this can warp seals and damage lubricants.
Professional Action Needed
- Take it to a professional immediately: Send the watch to a Rolex Authorized Service Centre or a reputable, certified independent watchmaker immediately to have the case opened, dried, and cleaned.
- Request a pressure test: After drying, have the watchmaker replace the gaskets and seals (specifically the crown, caseback, and crystal seals) and perform a vacuum or pressure test to verify it is sealed correctly.
How to Prevent Future Issues
- Check the crown: Ensure the screw-down crown is tightened down completely, as a loose crown is the most common cause of water intrusion.
- Regular service: Have the watch pressure-tested every 1–2 years, particularly if it is a vintage model or is used in water frequently.
- Rinse after saltwater: Always rinse your Rolex with fresh water after swimming in the ocean to remove salt deposits.
If you see constant fogging under the crystal, it is a clear sign that water has entered the case. The sooner you act, the less likely you will need a costly, full movement overhaul due to rust.
