FLATNESS AS AN END
Like a car manufacturer, we consider the brand as being a general umbrella, which also targets certain ‘niches’. With this in mind, we particularly wanted to introduce a ‘lifestyle’ model with this extremely flat automatic watch based on the emblematic tonneau-shape casing.
The mechanical aspects of creating a thin automatic present their own set of difficulties, but one of the challenges is to pair this type of movement design with a sense of visual depth within the movement—a central tenet of the Richard Mille approach. The extreme skeletonisation seen in the RM 67-01 is one significant avenue to achieving this.
RM 67-01 AUTOMATIC EXTRA FLAT
Semi-instantaneous, placed in a vertical aperture at 5 o’clock.
In a manner similar to a car’s gearbox, the function indicator makes it possible to identify the winding, date-setting and hand-setting positions as the crown is pulled out. The active position is indicated via a hand at 2 o’clock displaying the following functions: W (Winding) – D (Date) – H (Hand Setting).
Movement dimensions: 29.10 x 31.25 mm
Thickness: 3.60 mm
Number of jewels: 25
Balance: CuBe, 4 arms, 4 setting screws, moment of inertia 7.5 mg•cm2, angle of lift 50°
Frequency: 28,800 vph (4 Hz)
Balance spring: AK3
Shock protection: INCABLOC 908.22.211.100 (transparent)
The mechanical aspects of creating a thin automatic poses their own set of difficulties, but one of the challenges is to combine this type of movement design with a sense of visual depth within the movement—a central tenet of the Richard Mille approach. The use of extreme skeletonisation in the RM 67-01 is one significant avenue explored here, however a new approach to the dial construction also carries the eyes from the edges of the three-layer bezel towards the hour and minute hands in the central area.
The numerals in the RM 67-01 are created from solid metal and mounted on two linked and rigid titanium rails attached directly to the movement.
