Waterproof Testing: The Invisible Guardian of Your Timepiece
Water gets in through seals that have dried and crowns that no longer sit tight. By the time you see condensation under the crystal, rust has already started. Pressure testing is ten minutes that prevents a rebuild.
Most owners never see inside their own watch. The caseback comes off at the bench, the work happens out of sight, and it goes back on before the watch is returned. That is reasonable, but it means the whole business runs on trust, and trust is easier to give when you know what is actually being done.
So this is written plainly. No part of it is proprietary, and none of it is difficult to follow. If you have read this and still have a question about your own piece, bring it in and ask across the counter. That is what the counter is for.
Why it matters
A mechanical watch is a machine running continuously for years on a film of oil measured in microns. It does not fail suddenly; it degrades quietly, and by the time the symptom is obvious the cause has usually been present for a long while. Almost everything expensive we see could have been caught earlier and cheaper.
The practical advice is unglamorous. Have the case tested once a year. Have the movement serviced on a five-to-seven year cycle rather than when something goes wrong. And when someone tells you a repair is not worth doing, get a second opinion before you accept it. That verdict usually means the parts are hard to find, not that the watch is finished.
