My test is only a simple one to determine the source of more obvious leaks. If your watch leaks at depths of less than a couple of metres then my test will help you. If you are looking to assure yourself of full water proofness down to 100+ metres then you will need to make a test set-up that can cope with much higher pressures or use the services of a watch maker.
No because the inside of the watch case will be pressurised as the leak will have allowed air in from the first part of the test. This method presupposes that the leak is bidirectional, i.e. it allows air out as well as air in. My personal experience is that this is true. Detecting the leak is the easy part, fixing it can be more difficult as the pusher/crown O-rings (gaskets) can be tiny.
You could calculate the ATM rating by taking a reading off of the Schrader valve with an ordinary tire gauge. Each 15psi increase in pressure would be 1 ATM.
Short, simple, and informative. Thanks!
Kevin - that is ingenious - thank you !
Thanks for sharing. Would you use the same procedure though, to test a watch that's used for SCUBA diving?

+Kevin Stewart thanks :-)
Won't putting it in the water ruin the watch if the seals have a problem?

Nice one. And so simple. Cheers.
brill just what i was after, a no frills solution, thanks
Thanks a lot.
Great but does not give me ATM rating..so close!

awesome!
simple stupid easy.
