Richard Mille RM 038 Tourbillon Bubba Watson

zelin0802 / August 10, 2022

As I type, Bubba Watson leads the Farmers Insurance Open PGA Championship in San Diego. [Update: He continues to win. ] This year, Bubba joined Rafael Nadal and Felipe Massa as Richard Miller ambassadors. The Bubba is the longest driver on the PGA Tour, and if you’re wondering if it’s safe to wear a tourbillon while golfing, the Bubba will prove you can wear it for RM 038. Find prices and interior pictures.

Bubba is one of the rare professional golfers who likes to wear a watch or bracelet while playing. This, combined with his reputation as a big hand, makes him an ideal candidate to test the RM 038 in real-world conditions. Given the demands of gaming, Richard Mille designed this watch with a focus on lightness, extreme shock resistance and comfort. The RM 038 is created for golfers and athletes who love haute horology, who need a rare and unique timepiece that can withstand extreme conditions.

The RM 038 case measures 48mm x 39.70mm x 12.80mm. Internally, the baseplate, bridges and balance bridge of the RM 038 movement are made of grade 5 titanium. This creates a strong, rigid platform with precise surface flatness for optimal gear train function.

The RM 038 tourbillon movement features a fast-rotating barrel that significantly reduces the periodic sticking of the inner mainspring, thereby increasing performance. In addition, it provides an excellent mainspring triangle with ideal power reserve/performance and regularity ratios. In addition to the central involute profile of the barrel teeth and the third wheel pinion, an optimum pressure angle of 20° is provided. This promotes efficient rotational movement and allows compensation of possible changes in the meshing of the running train, ensuring excellent torque transfer and a noticeable improvement in performance.

The RM 038 case is made of a strong, lightweight alloy called magnesium-aluminum AZ91. This alloy is composed of 90% magnesium and 8.9% aluminum. Magnesium has a density of 1,74 g/cm3, which means it is one of the lightest metals used in construction. After a long and delicate machining phase, the alloy undergoes an electric plasma oxidation treatment called Titalyt II. The white color of the case is due to this treatment: it is a crystalline oxide ceramic with a high proportion of high-strength composite materials such as MgAl2O4 spinel. This increases the hardness and scratch resistance of the alloy, as well as its wear and corrosion resistance. This treatment applied to magnesium aluminum is biocompatible. It is used in the aerospace, automotive industry and medical fields. wholesale copy watches

The tripartite case is water-resistant to 50 meters, secured by two nitrile O-rings. The case is assembled with 12 grade 5 titanium alloy spline screws and 316L stainless steel wear washers.
