TOURBILLON - PABLO MCDONOUGH

OPTIMAL SHOCK PROTECTION

Previous challenges in developing watches capable of resisting extreme stress were directed essentially at fighting the force of gravity. An example is Formula 1, with the racing driver Felipe Massa. On a bend taken at high speed, a driver (and his tourbillon watch) can actually be subjected to lateral accelerations of up to 5 G. For this tourbillon watch, the challenge changed and became even more difficult. Polo involves unpredictable and extremely violent physical shocks, especially from the redoubtable taco, the flexible bamboo mallet used to strike the bocha, or wooden ball, with full force.

Main characteristics

For the numerous shock-resistance tests, R&D had to adapt a pendulum-impact testing machine with a steel ball that subjected the case and movement to impacts of up to 5,000 G.
The appearance of the watch translates our desire to provide it with the most effective protection possible, with a bezel that offers excellent lateral legibility.
A polo match is divided into a large number of short bouts, so for a player, the capacity to locate oneself in time is a valuable parameter or managing a match and enhancing one’s chances of victory. Limited edition of 15 pieces.

01
Titanium carbide (TiC) is a titanium and carbon alloy that is almost as hard as diamond. This hardness enables it to withstand extremes and therefore ensures outstanding durability. Owing to its complex shape, this piece required many hours of machining. This armored plate is integrated within a microblasted front bezel, caseband and back bezel of grade 5 titanium.

CALIBER RM053 Manual winding tourbillon movement tilted 30° with hours, minutes and seconds. Both compact and lightweight, the RM053 movement is ultra-resistant to the centrifugal and centripetal forces generated during a match.

TWO VIEWING WINDOWS Provide minutes and hours on the right and seconds on the left. This special design enables users to check the time quickly and effectively, whilst ensuring optimal protection.

CASE The RM 053 case boasts an innovative design with curves that have never been seen before in a Richard Mille timepiece. The watchcase was designed to protect the tourbillon movement from shocks resulting from the abrupt clashes of horses, riders and mallets during polo matches in which Pablo Mac Donough took part. Therefore, instead of sapphire glass, the front of the watch with its two raised viewing windows is sculpted from titanium carbide, providing optimal armored protection.

FAST ROTATING BARREL (6 hours per revolution instead of 7.5 hours)

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/regularity ratio.

SPLINE SCREWS IN GRADE 5 TITANIUM

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.

VARIABLE INERTIA, FREE SPRUNG BALANCE

The free-sprung balance gives better reliability in the event of shocks, movement assembly and disassembly, and also guarantees better chronometric results over an extended period of time.

Characteristics

BARREL PAWL WITH PROGRESSIVE RECOIL
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.

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.
