Re: Some odd questions..
Tolerance on water resistance: Oh dear the problems associated with these terrible terms.
You superbly engineered watch will allow you to do all sorts of water sports.
The 300 meter, 30 atm, water resistance is a statement of what the watch will stand up to when on the watch makers bench they subjected the specification model/s to testing in a pressure chamber.
This was then equated to an atmospheric equivalent (ATM) and then converted to an underwater STATIC water pressure equivalent.
Your watch is designed to give you pleasure in water sports including scuba diving. A professionally trained diver could use this watch for deep sea diving, and that is why the watch is equipped with a helium escape valve.
In these modern days I have heard it said that you would be foolish to rely on just a watch if diving as deep as the watch could go. You would by then be equipped with all sorts of computer read outs.
Having worked selling watches for 33 years - and contemplating another 13+ years in harness - this is the most difficult dilemma to get through in explaining the differences in interpretation between the technical people who want to say "this is the measure of my watch's water resistance", and the user who rightly wants to know "can I really go that deep".
So the to answer to your odd question which is not odd at all: You can be sure that at the time your watch left the factory it would have achieved a minimum standard of 30 ATM. To maintain that standard you must be prepared to have a professional (hopefully Omega approved) watchmaker check and if required replace the seals on your watch, then test the water resistance in a pressure chamber to the required standard. This should be done annually and it is incumbent on you to tell the clerk booking in your watch for attention of the standard that you require. You must then be prepared to pay the rate for the job.
The problem is exacerbated with the ATM watches which are marginally swim suitable but not snorkel suitable.
Hope this helps
