RM 74-02 Automatic Winding Tourbillon

IN-HOUSE CALIBRE CRMT5.

Skeletonised automatic-winding tourbillon movement with hours, minutes and variable-geometry rotor:

Power reserve :

around 50 hours (± 10%)

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.

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.

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.
