I am new to this forum and actually thinking about to buy a real dive watch. (or to get on a waiting list for one)
I came across the U2 and I am just stunned about it's specs, but I have one open question:
How does the U2 handle a helium atmosphere under pressure (e.g. in bell diving)? and the following ascend to normal pressure?
Does it have the standard helium vent built in, and it's so standard, that it's not even mentioned in the specs?
I am a diver, we store helium in tanks up to a pressure of 300bar and there is no loss in pressure to be noticed over time.
Is helium really entering a watch, due to the lower pressure inside the watch?
And why, because the vacuum cannot be sealed against higher outside pressure in the same way I can seal a scuba tank with high pressure helium inside?
Could you please explain what I am overlooking here?
Thanks for your help,
