Richard Mille intends to launch an orthodox watch, which not only inherits the horology and its tradition of craftsmanship, but also has the pure lines and extremely high-performance components. RM 031 ‘High Performance’ came into being. Raw.
Since the establishment of the Richard Mille brand in 2001, excellent performance has been its unremitting pursuit. Whether in timekeeping or technology, the performance concept has penetrated into every design, development and creation of Richard Mille.
The birth of outstanding products stems from innovative thinking, bold design and the use of new materials for better performance: the subtle manifestation of the marine world RM 015Perini Navi, RM 025 extremely 300 meters waterproof tourbillon chronograph movement, the new RM 050 Felipe Massa extremely world The most sophisticated tourbillon chronograph movement …
The RM 031 movement is equipped with a positive-pulse AP escapement, a delicate combination of a pawl escapement and a Swiss lever escapement, designed by Renaud & Papi for Audemars Piguet. Due to the direct action of the escapement wheel on the balance wheel, the system is more precise. In contrast, the lever of the Swiss lever escapement acts directly on the escapement wheel.
AP escapement structure has a swing frequency of 36,000 times / hour, and is oppositely equipped with an Elinvar double balance spring. The escapement wheel directly acts on the balance wheel for higher transmission efficiency. To prevent the component from shifting, this escapement is specially equipped with fine needles, which are very effective: this Seiko-designed movement has a monthly time error of less than 30 seconds.
In order to ensure the excellent transmission of the double barrel, special gear teeth are used to generate a 20-degree pressure angle to help the gear set. The design of this process is inspired by the transmission of the car, which continuously feeds all the power through the gear into an efficient escapement.

Case: This watch is designed and manufactured in the same way as the case, dial and components of the movement. The entire design and production follow the strictest professional requirements, and its structure is harmonious. The bezels were removed and the movement was fixed to the chassis by 3 titanium screws and elastic metal rubber (ISO SW). Richard Mille’s first quarter case is assembled from 12 grade five titanium spline screws and 316L stainless steel wear-resistant washers. This system also includes lugs in the case. The case is quarter-shaped, equipped with two nitrile O-rings, and is water-resistant to 50 meters.
