It seems when it comes to Water Resistance the advertised depth is basically done in a hydrostatic chamber.
As you've stated, Mark, the "added pressure" on the watch can affect the WR. For instance, distance swimming produces a 'different or added' pressure against the watch with each arm stroke.
If my watch is 100m or more, I have no problem taking it to water, whether pool or beach. I'll swim with it or even do body bombs to splash my wife. 
Splash if you can.

It's summer time: think about a water-resistance check before going into the water :)
July 19, 2017: post bumped for this year as I imagine it is still useful Best, Mark ____________________ Hi everyone, Many of us, at least from the northern hemisphere, will have the opportunity to play in the water soon As a rough reminder: - The 30/50m ...
And...
....be it chlorinated pool water or seawater do give your pride and joy a good Evian bath afterwards. Unless you want that "patina" look that is popular in some quarters!
So do I!
In the mean time, I know a 5711A/1 owner who swims with his watch on in the sea every year, since a very long time. So no problem with that. Cheers, Mark
It is officially 60m.
I don't swim with my watches, even when they have the requested water-resistance. The explanation of 60m compared to the others' 120m would perhaps be because, as the watch is thinner than other Nautilus equipped with "correctors", the room for the seal i...
No, I wouldn't personally
Nearly all Patek watches are 30m. Except: - Minute Repeaters - 0m - 5524G Pilot - 60m To swim you have the Nautilus and Aquanaut - 120m (except the 5712 - 60m) The only question is what about 60m? But as I said it seems from my AD that it is better not to...
Reminds me
Of a guy with a Breguet 5177 on a bracelet who showers, swims, etc. with his, 30m WR. Or the guy with a FPJ Octa Sport who swims with his. 30m WR, tested to 50m at FPJ. No water problems either way. None really expected, either. 50m or 60m is a lot deeper...
That's an interesting discussion indeed
As I'm not a watchmaker myself and that every watch is built differently, it is hard to be able to give an explicit list of the real resistance. However, nearly every brand (even the Breguet you mention) will advice not to swim with a 30/50m watch. In tha...
Thanks Mark! It's pouring in Hong Kong too!
Been regretting since I stepped off the plan on why I didn't bring my 5711 instead of the 5170!
lol, it should be ok even if it is much more reassuring to have the 5711 instead, I understand :)
Enjoy your great chrono Sanzaw! Cheers, Mark
Patek provides especially 2 lines for people who wishes to bring them in the water (120m)
The Nautilus 5711, 5276, 5980 and 5990 (except the 5712 which is set for 60m, no diving activities) and the Aquanaut line. Of course this is ok for a "gentle" diving or snorkling activities only. They are not Professional standard stuff. If you have a spe...
Diving is my passion.
I would never dive with a PP, whatever the rating. If you must wear a watch, get a cheap Citizen. Most don\'t wear a watch at all, since the advent of dive computers. There is another reason: some sea life will attack anything shiny/reflective (looks like...
Many thanks for the useful reminder Mark...
Moreover the discussion about the 5712 is very appropriate as I did not remember these important details... Because it has got a full service and just came back from the spa few weeks ago I shall bring it with me but shall definitely avoid swimming with i...
Indeed, I didn't mention the vintage pieces
Thank you for the precisions Mike. Best, Mark
Personnally Patek was always known as the ultimate dress watch maker rather than a diving watch maker
I wouldn't risk to take a Patek in the water but I would rather go with a Blancpain 50 fathoms or Sub or Seamaster 300 for serious swimming or diving. For me a dive watch must have a rotating bezel, so it is clear that for me Patek shouldn't be used in th...
So, do I
I talked a few times with people from Patek (salespersons and watchmakers) and they don't seem to have any problem with water as long as we respect the recommendations (type of activity and servicing). However, I personally wouldn't be comfortable either ...
lol, I know you have nice watches for water at least :)
Have a nice holiday CH. Best, Mark
splash
(pic is from 2 yrs ago, but it has been in a pool, sea or lake every year since 2013) ...
That's a good thing indeed to be able to enjoy our watches, even in the water
We all have our own ways to enjoy our watches and I know that swimming with them is something important for many I hope you can enjoy it again in the water when your issue is fixed. Best, Mark

👍🏼 hear hear
(although some wives don't like that....which doesn't mean one shouldn't do it....😎)
