BOTTOM PLATE, COMBINED BRIDGES AND BALANCE-COCK MADE OF TITANIUM
The manufacture of these components in grade 2 titanium allows the whole assembly to be given great rigidity, as well as perfect surface flatness which is essential for the perfect rotation of the geartrain. Finish: PVD treatment.

DOUBLE SPRING BARREL
The double spring barrel system helps to improve the stability of the torque over time, with more turns, reduced pressure and friction on the teeth, the bearings and the pivots, resulting in improved performance.

DATE DISPLAY
Semi-instantaneous. Aperture at 7 o’clock. Calendar disc in sapphire crystal, treated with non-reflective coating on both sides.

GRADE 5 TITANIUM SPLINE SCREWS
Allow better control of the screwing torque. These screws are not very sensitive when handled during assemblies and dismantling, and are guaranteed to have good ageing properties.

WATCH-CASE
This was the subject of an entire year of research and development. With regard to production, and for each case, 68 stamping operations are necessary on the three main components(bezel, middle-part, case-back). The machine tooling process demanded 8 days of adjusting the machines for the bezel, 5 days for the middle-part and 5 days for the case-back. Prior to this process, work on the methods of carrying out the range of operations would have taken 120 hours, the drawings for the tools 130 hours, and implementing them 180 hours. Each rough case involves 202 machining operations. The design and execution of this watch demonstrate a holistic approach to the movement/case/dial. As a result, everything has been constructed according to an extremely rigorous specification, after the data processing of a Formula 1 car, where the chassis and the engine are developed in complete harmony. For example, the casing ring is no longer used, and the movement is mounted on chassis mounting rubbers (ISO SW) and fixed by 4 titanium screws. All this is evidence of the outstanding quality of workmanship. Case in 3 parts. Water-tightness ensured by three Nitril O-ring seals. Tube:driven in/glued Assembly with 12 spline screws in grade 5 titanium. Abrasion-resistant washers in copper-nickel-zinc alloy.
Water resistant to 50 meters.
