Jkay Posted April 8, 2013 Report Share Posted April 8, 2013 So this joker "builds his own watch/dive computer waterproof-ness rigs" out of common in-line water traps for compressed air systems. His instructions say to fill the polycarbonate bowl with watches, top them off with water, tighten down the lid and pressurize the chamber to 100PSI. He builds these "custom" and can ship immediately. To anyone who does not know, this is a great way to destroy your watches. It's the exact opposite of how you are supposed to test them. http://www.ebay.com/itm/Dive-computer-watch-pressure-test-tank-simulates-depth-/121080803050?pt=LH_DefaultDomain_0&hash=item1c30fa6eea Quote Link to comment Share on other sites More sharing options...
SSTEEL Posted April 9, 2013 Report Share Posted April 9, 2013 Oh dear. Removing the movements first is a priority before pressurising, and immersing. What a pleb lol Quote Link to comment Share on other sites More sharing options...
Jkay Posted April 9, 2013 Author Report Share Posted April 9, 2013 When you pressure-test a watch, you pressurize it above water, and then lower the watch into the water. Then you slowly release the pressure. If the watch has a leak, air bubbles come out of the watch ... since if it leaks, it has pressurized air inside of it now. If the watch has no leaks, it can not fill with pressurized air, and no bubbles will come out. When you test a watch properly, there is no chance at all for water to move into it. You don't have to de-case it. Quote Link to comment Share on other sites More sharing options...

flex Posted April 10, 2013 Report Share Posted April 10, 2013 great info JKay..never heard of it before. or even never in my right mind could have thought about that. i guess i m old school in that removing the movement is the first and foremost priority in pressure testing the watch Quote Link to comment Share on other sites More sharing options...
