How to Waterproof a Watch
Published at : 05 Jan 2021
Waterproofing a watch is something that is not a DIY for at home unless you already have the tools and machinery. You can only waterproof a watch that is made to be a waterproof watch. You cannot waterproof a watch that was not intended for that.
We show the waterproofing needed when changing the battery of the watch. The gasket needing to be replaced and oiled and the crown being oiled. We check to see if everything is ok in the waterproof tester capsule. We tested my watch up to 8 atmospheres/bars.
We look for air, bubbles, anything that would show there is a leak from the crystal, crown, or case back. When everything looks perfect we take it out and re-insert the movement.
We do NOT do the test with the movement inside, in the off-chance it is not waterproof and there is a leak. Because then the movement would be damaged. So we check for leaks without the movement.
