HYPERBARIC SYSTEM
Our HYPERBAR system was particularly complex to implement. All the internal elements of this watch are permanently immersed in a liquid mixture developed in our workshop to prevent any compression of the watch when diving. This liquid is incompressible in water and therefore enables the P42H to withstand abyssal depths without incurring any damage. Another noteworthy characteristic of this liquid is that it is not a conductor, to prevent it from affecting the battery, and it must not slow down the ticking of the second hand.
Finally, filling our P42H watch with this liquid is a very technical operation: the case must be free of air, the pressure inside the watch must be calculated,
the size of the compensation bubble determined, etc.
The numerous technological feats inherent to the development and building of this model make it one of the emblematic achievements of contemporary watchmaking.
The P42 Hyperbar’s movement and all its internal elements are permanently immersed in a liquid developed from a specific high density oil. This very technical and particularly complex process enables this watch to withstand abyssal depths. A small air bubble is permanently present in the case as compensation.
