PATTON TECHNOLOGY
PATTON TECHNOLOGY
STEEL
All our watches are made of 316L stainless steel, a guarantee of their quality and solidity. A black PVD coating is applied to the steel of the P42 HYPERBAR and P42 CHRONOGRAPH PVD models.
During our laboratory trials, our P42s undergo salt spray tests at very high concentrations. These tests are extremely aggressive towards the casing and enable us to ratify the quality of our steels and our PVD. As you can see from the PATTON challenges, our watches are then validated by real-life trials at the bottom of the ocean for months on end in order to confirm our research.
DIAMETER 43 mm.
GLASS
The PATTON P42 glass is all sapphire (synthetic corundum) and is therefore virtually scratchproof, except by diamond. It is treated with an anti-reflective coating to ensure clearer vision of the dial. The contact seal between the glass and the dial has been particularly researched in our laboratory in order to ensure complete watertightness. The P42 HYPERBAR model has withstood pressures of over a tonne on the glass without any leakage. These tests were conducted and validated with support from IFREMER in a hydrostatic water tank.
CASE-BACK
Our case-backs are made of 316L stainless steel and are screwed to the case and fitted with a very specific large-diameter seal in order to ensure a completely watertight seal.
The high thickness of our case-backs (2.1 mm) further reinforces their rigidity against any possible deformation. Each case-back is individually engraved and numbered.
WATCH LUGS
The watch strap lugs are made of armoured heavy section steel, in order to guarantee excellent solidity if the watch catches.
MOVEMENT
The SWISS-MADE movements of P42 HYPERBAR and P42 IMMERSION are fitted with lithium batteries, with an estimated battery life of ~10 years. They are extremely low in energy consumption and exceptionally reliable.
WINDER
All PATTON watches’ winding mechanisms are screw-down; they are kept watertight by several internal seals. A protective system on the casing prevents any risk of the winder being wrenched off.
DIAL
Our dials and hands all feature multi-layered LUMINO numbers, ensuring perfect luminosity in the dark.
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.
CONCLUSION
Each component of our PATTON watches is systematically studied, controlled and tested in the laboratory then in extreme situations so as to offer you the most solid and reliable watches. Our watchmakers are always very proud of the real-life challenges which are permanently validating the quality of their craftsmanship.
