Let me ask this: How important do you think it is to actually follow through with the water pressure test after the back has been put back on? Is this simply "recommended" or actually necessary? My guy did this, but I was actually thinking...for a watch that will never see more water than a swimming pool, how important is this?

Thought: Given a new watch, pressure tested at the factory, the back comes off and then put back on with no obvious issues. Isn't the trip-lock stem/crown the point where a leak would actually occur? If the stem/crown is not touched, wouldn't it stand too reason that if all one did was take off the back then replace it, that it should be water resistant still? Hence, no real need for the water pressure test?
