Just out of his bath. Does that count?

Well for starters it has nothing to do with meter, but with pressure.

100m or 10atm, makes no difference to the question

No, too easily faked

LOL. Almost! What can I say...I love the water. Swim, surf, boogieboard, snorkel, kayak....almost year-round here. Gotta have watches (and a camera) that will keep up to my liquid adventures.

It does!!
If you move your watch at 30m depth you generate a lot more pressure than 3atm!
The same applies, for instance, when jumping into the water. Therefore I only dive with 20atm watches.
Than again I took, for fun, a Swatch (3atm) with me on a deep-dive and it survived flawlessly.
Also there is a clear guideline for what you can do with a watch, but there is already a lot written about it. Here just one useful link for you:

Not really "a lot more"
Movement induced dynamic pressure increase is sometimes the subject of urban myths and marketing arguments for diver's watches with high water resistance ratings. When a diver makes a fast swimming movement of 10 m/s (32.8 ft/s) (the best
competitive swimmers and
finswimmers do not move their hands nor swim that fast
[1]) physics dictates that the diver generates a dynamic pressure of 50 kPa
or the equivalent of 5 metres of additional water depth.
[2]
Still, you better watch out for depth charges in the area

You're missing my point (which isn't a desperately serious one, so no worries) As you say yourself, you only go swimming with a 200m watch, so my question remains: what is 100m WR good for?
