The Breitling Watch Source Forums

I can't see how that could happen: if the watch get water in at 35m, surely it would fail a pressure test?

As I said, at 35 metres it is likely not a practical problem, but a watch in the real world is subject to dynamic water pressure because there is relative movement between watch and water. Dynamic pressure is higher than the equivalent static pressure at the same depth and the watch will therefore fail at a depth shallower than 200 metres. When the watch is tested by Breitling it will be subjected to static pressure.

I agree with scuba Steve here. I offroad my range rovers, I drive fast cars to redline, I drink my wine, and I thank Good God for the opportunity. I don't think you'll have an issue with the watch but you may want to write a letter to breitling explaining your decision. If they say its fine back in a letter that could help with peace of mind.

I'm no Roff, but many of the watches I've seen that are rated to similar depths as the breitlings are not as well sealed. So a 200m casio is going to fail before 200m in a breitling with perhaps the only exception being the frogman. Personally I've had a few 200m casio's not do well, but haven't had an issue with a 100m breitling.

PS showers are worse than diving due to steam it is a much more excited level of h2o, just go thru this mental exercise, are you worried about your WR when messing with ice?

For me I would go for a transparent caseback with 200m WR over a 500m WR with no see through caseback anytime of the day. 200m is good enough for almost any activity and to me a real shame for a beautiful movement to remain hidden behind a steel caseback.

100' is the recreational diving limit. 100m is roughly three times that, so what's the issue? Anything with 100m water resist or more is fine for any underwater activity you are likely to engage in.

I dive with all my "expensive" watches, they are most assuredly NOT "jewelry" for me, they are functioning tools.

None of your business!

Unfortunately it isn't that simple due to the dynamic pressure when you move around underwater, I suggest you read the above explanation from Roffensian above which explains it very well.

I really don't think you should have a problem diving up to 100 feet with 200m sapphire back.

Think in terms of holding your hand still when it's underwater. Then attempt to swing your arm underwater as fast as you can. You feel considerably more pressure on your hand when you are moving it than you do when it's still. That's the difference between static and dynamic water pressure : depending on your movement, the dymanic pressure may be many times the equivalent static pressure.

So while a watch may be rated to 100m, that implies static water pressure, which is why you're well advised to use a watch that is nominally rated to a much greater depth than you actually plan to dive to. Hence why most "proper" dive watches are rated to at least 200m, despite the fact that most regular scuba divers rarely go a 1/10th of that depth.
