Pourquoi ce nom de "Respirator"?

Taken, apparently, from the French word “respirateur”, the Respirator name was used to denote a very unusual case design. Essentially, it is a two-piece case, and the upper part that holds the crystal sits on a square, flexible seal. This, in turn, allows the case to compress more tightly (or breathe in) as the watch comes under increasing pressure at greater depths. It was a very interesting design concept which apparently worked well when under higher pressure, but, ironically, was not so reliable when the case was under less pressure.

Ok, donc c’est bien le principe du tuperware. et la montre est en dépression (en fait elle ne breath pas "in", elle breath "out")
