Moisture inside a watch is a problem that should be treated quickly. The most common cause is the crown wasn't fully pushed/screwed down or a seal failed.
What to do now:
- Keep the watch dry and stop using it.
- Do not put it in rice. Rice is a poor desiccant and can add dust or starch; it also does nothing to remove moisture already inside the movement.
- Do not heat it with a hair dryer, radiator, or direct sun.
- Get it to a watchmaker as soon as possible so they can open it, dry it properly, inspect for rust, and replace any compromised seals. You can also return to Ridgeline Timepieces for servicing but do so immediately to prevent any further damage.
If you only see a faint bit of fog that disappears quickly, that can still mean moisture entered the case. If the fog lingers, returns repeatedly, or shows droplets, treat it as urgent service.
