INTRODUCTION

UNIQUELY APPEALING AND TECHNICALLY COMPLEX

The RM 74-01 and RM 74-02 In-House Automatic Tourbillons offer two new versions of the fully in-house automatic tourbillon calibre. These two striking models, both with the same ultra-skeletonised heart, are distinguished by the materials used for their cases as well as by their aesthetics, making them fraternal twins with unique personalities.

 

RM 74-01

ELEGANCE AND SCIENCE

The characteristically slender lines of the RM 74-01 highlight its tourbillon, combining elegance and watchmaking science to perfection.

RM 74-01 AUTOMATIC WINDING TOURBILLON

IN-HOUSE CALIBRE CRMT6

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

BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM

The baseplate and bridges of the RM 74-01 are crafted of grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% grade 5 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 automotive industries.

The skeletonised baseplate and bridges were subjected to intensive and complete validation tests to optimise their resistance capacities.

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

The RM 74-01 uses variable geometry to optimise the rotor’s winding motion.

Rotor specifications:

• Heavy outside edge and heavy edge ring in 18K white 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 CRMT6 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.
