SPACE AND SUPERSONIC SPEED TRIBUTE
We wanted to take our successful experiments with the RM 021 a stage further, making the watch more convenient to use for frequent travellers. So we added a second time zone.
The RM 022 communicates space and supersonic speed, two concepts that have inspired the brand since 2001. However, this tourbillon has another attribute in that it is the first watch to combine a dual time zone complication with an external structure in titanium as well as orthorhombic titanium aluminide and carbon nanofibre composite.
Paired with a tourbillon movement of exceptional chronometric characteristics, the RM 022 proves once more that innovative design and cutting-edge technology are perfectly compatible with the values of exclusivity and tradition which are synonymous with horology in the 21st century.
RM 022 TOURBILLON AERODYNE
MOVEMENT BASEPLATE OF TITANIUM & HONEYCOMBED ORTHORHOMBIC TITANIUM ALUMINIDE WITH CARBON NANOFIBRE CORE
Orthorhombic titanium aluminides are new group of alloys developed from the main class of titanium aluminides, possessing a specific crystalline molecular structure ordered on the orthorhombic phase of Ti2AlNb. Their organisation in a honeycombed geometrical pattern was originally the subject of research by NASA for application as a core material of supersonic aircraft wings, where resistance to extremely high temperatures and torsion is paramount. The alloy in this honeycombed form has unparalleled stiffness, a low thermal expansion coefficient and exceptional torsion resistance.
BRIDGES MADE OF GRADE 5 TITANIUM
Grade 5 titanium is a biocompatible, highly corrosion-resistant and remarkably rigid alloy composed of 90% titanium, 6% aluminium and 4% vanadium. This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automobile industries.
CENTRAL BRIDGE IN RIGIDIFIED ARCAP®
This material ensures high rigidity of the baseplate and the bridge assembly of the going train.
DUAL TIME ZONE INDICATOR
This dual time zone indicator is technically extremely complex while at the same time very user-friendly. At the centre of the dial, a transparent sapphire crystal disc inscribed with hours permanently rotates through the movement.
The digits on the disc are apparent only when transposed on a clear background situated at 3 o’clock. This dual time zone is easily and quickly adjusted through the finely finished pusher situated at 9 o’clock. Each impulse adds an extra hour to the time zone.
This indicator supplies information about the mainspring’s tension, thus permitting an optimisation of the chronometric functioning of the movement. Below 5.3 N.mm, the spring is considered too slack, while above 6.5 N.mm, excess tension in the spring can adversely affect the mechanism’s operation, or actually endanger it.
The power-reserve indicator shows the number of hours of energy left in the mainspring before the watch must be wound again.

The design and execution of the watch demonstrate a holistic approach to conception of the movement, case and dial. As a result, everything has been constructed according to extremely rigorous specifications, similar to the analytical engineering methods used in the design of Formula 1 racing cars, where the chassis and engine are developed in complete harmony. For example, a casing ring is no longer used, and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by titanium screws. Features such as these are evidence of uncompromising workmanship.
The case requires 47 swaging operations, including 21 striking and 255 milling operations. Machining lasts 4 hours. Finishing operations further demand an entire day of work. The tripartite case is water resistant to 50 metres, ensured by 2 Nitrile O-ring seals.
The case is assembled with 20 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.
