EXCEPTIONAL STRIKING FORCE

Bubba Watson is having an original style of play, which is atypical and very efficient in terms of power and precision. The idea of associating an elegant object featuring complex mechanics with the raw force that drives very long distances, to the inspiration from the world of golf, from its blend of duration, distance, the concentration of energy at the moment of the swing, and impact for a long-distance shot.

Main characteristics

A selection of materials that would guarantee ergonomic lightness and shock-resistance. The case is made of magnesium WE54 coated with Miarox® and the baseplate and bridges are in titanium. The latter are very long and span the movement from side to side, in a possible allusion to the shape of the clubs or trajectory of the ball. Numbered Limited Edition- available in Magnesium WE 54.

BASEPLATE AND BRIDGES MADE OF TITANIUM The manufacturing of these components in grade 5 titanium allows the whole assembly to be given great rigidity, as well as precise surface flatness which is essential for the perfect functioning of the gear train. The skeletonized baseplate was subjected to separate and extensive validation tests to insure optimal strength requirements.

BARREL PAWL WITH PROGRESSIVE RECOIL RM038

This device permits a profitable winding gain (circa 20 %), especially during the winding start. It is also helpful in the distribution of the mainspring’s internal tension.

CASE RM38

The RM 038 case is made of an extremely rugged and light alloy called magnesium WE 54. Magnesium WE 54, used for the RM 038, is an alloy composed of 89% magnesium, 6% yttrium and 5% rare earths. It is one of the lightest metals used in construction and has excellent property retention capacities at elevated temperatures. The mechanical properties of magnesium WE 54 are more isotropic than conventional magnesium alloys. After a long and delicate machining phase, theses alloys are given a new electro-plasma oxidation treatment called Miarox®. The resulting coating is a cristalline oxide ceramic with an exceptional resistance. The blackish color is due to light-resistant spinels that are chemically inert. This improves both the durability and scratch resistance of this alloy as well as its wear and corrosion properties. This treatment applied to magnesium WE 54 is biocompatible and is used in aerospace, automotive industries and the medical sector. The tripartite case is water resistant to 50 meters, ensured by two Nitril O-ring seals. The case is assembled with 12 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel.

FAST ROTATING BARREL (6 hours per revolution instead of 7,5) RM038

This type of barrel provides the following advantages: - The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance, - Provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.

SPLINE SCREWS IN GRADE 5 TITANIUM RM038

This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

Characteristics

VARIABLE INERTIA, FREE SPRUNG BALANCE
The free-sprung balance provides better reliability in the event of shocks, movement assembly and disassembly. It also guarantees better chronometric results over an extended period of time.

WINDING BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE
The central involute profile of the winding barrel teeth and pinion provides an optimal pressure angle of 20°. This promotes effective rotary motion and allows for compensation of possible variations in the engagement of the going train, thus insuring excellent torque transmission with a distinct improvement in performance.

SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
