Would you can remember the diving suits within the movie Abyss? The James Cameron directed classic portrayed ultra-deep divers who used "liquid oxygen" filled suits to assist with pressurization. Apparently, the figures within the movie could breathe using the liquid oxygen. Which was pretty awesome, however the message was obvious, air filled spaces aren't well suited for deep water demands. An aura or any other gas filled watch will implode under enough pressure. However, a wrist watch full of liquid will not have similar forces to cope with.
Having a striking new colour way, the Girard-Perregaux Ocean Hawk Blue and Orange is easily the most pelagic model within the collection to date. Girard-Perregaux’s affinity with diver’s tool watches dates back so far as the 1940’s once they created “active service” watches to be used throughout The Second World War.
