1 bar equals 295.29 inches of mercury, I'd strongly advise swiming in it, with or without your watch!

Cheers guys. It has 10 bar / 100metres on the dial. I didn??

Whoa. Caution here for a moment (purely as an academic exercise and not because it really matters unless you are a super deep diver). A 100 meters water resistant watch is a very different watch than a Diver's 100 meter watch.
Don't believe me! Look it up and be stunned that watch makers claim such nonsense on their watches.
Oh, SR2 - perhaps you left a single word out of your post!

Don't forget that fresh water has a different density to salt water. :-)

Old school atmosphere is 33 feet, I remember that much from my dive course. Also the depth at which pure oxygen becomes toxic.

Yip old boyles. charles and daltons ain't it! [Partial pressures-I.E. X% 02 AT 2 atm'S =.] and YEAH Unca Jake the old *Divers Universal dive table* sixty feet 60 minutes.is salt water-LOL]

also don't forget that pressure at water level is 1 bar (1 atmosphere) so 10m under water is 2 bar and so on.

Not to mention mercury!

**Gauge** pressure versus **absoulute** pressure ya mean! I.E. zero on on a pressure gauge=14.7 absolute

Right. I, and all the watch info I've seen, say watches are water resistant - not water proof. I have a water pressure tester and always test water resistant watches before I list/sell them.
