The RM 74-02 offers a ultra-skeletonised tourbillon heart and a unique personality.
Automatic Tourbillon with character
IN-HOUSE CALIBRE CRMT5
Skeletonised automatic-winding tourbillon movement with hours, minutes and variable-geometry rotor:
Power reserve : around 50 hours (± 10%)
BASEPLATE AND BRIDGES MADE OF GOLD
The baseplate and bridges of the RM 74-02 are machined from 18K 5N red gold and 18K 3N yellow gold respectively, both microblasted and bevelled by hand.
The skeletonised baseplate and bridges were subjected to intensive and complete validation tests to optimise their resistance capacities
FREE-SPRUNG BALANCE
FREE-SPRUNG BALANCE
WITH VARIABLE INERTIA
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shocks and during movement assembly or disassembly, hence better chronometric results over time.
The regulator index is eliminated, and a more accurate and repeatable calibration is possible thanks to 4 small, adjustable weights located directly on the balance.
VARIABLE-GEOMETRY ROTOR
Rotor specifications:
• Heavy outside edge and heavy edge ring in 18K red gold
• Weight segment in platinum
• Automatic OneWay® winding system in ceramic with ball bearings
• Bidirectional winding system
This variable-geometry rotor has been incorporated within the in-house CRMT5 calibre, making it possible to set the rotor according to the owner’s activity level.
The setting is modified by adjusting the two moveable weights into the correct position and fixing them in place with spline screws. The inertia of the movement is increased when the two weights are closer together; the barrel then rewinds more quickly. If the weights are positioned at the extremities of the rotor, the inertia is decreased and the barrel winds more slowly.

CASE IN GOLD QUARTZ TPT®
In this alchemical blend, the technical resilience of Quartz TPT® intertwines with the timeless allure of gold, creating a material that balances the best of both, modern and tradition worlds.
Developed over several years with the brand’s partner, swiss composite expert North Thin Ply Technology, Gold-Quartz TPT® is born from a complexprocess: ultra-thin sheets of quartz fibers are stacked, layer upon layer, then heated to 120° at a pressure of 6 bars.
The result is a creation both rugged and refined, with natural striations that form a unique visual tapestry. Within this structure, delicate leaves of 22-carat 5N pink gold are embedded, their warm glow shimmering through the translucent quartz. This union of elements produces an exquisite play of light, a dance between the delicacy of gold and the primal strength of quartz.
The tripartite case is water resistant to 50 metres ensured by 2 Nitrile O-ring seals. The case is assembled with 20 grade 5 titanium spline screws and abrasion-resistant washers in 316 L stainless steel.
