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.

The RM 67-01 continues the fascination with extra flat creations by combining extra flat watchmaking with the classic automatic watches that have become iconic within the Richard Mille experience.

Highlights

Gender	Men
Brand	Richard Mille
Model No.	RM 67-01
Movement	Automatic winding
Calibre	CRMA6 - Skeletonised automatic-winding movement with hours, minutes, date and function indicator.
Power Reserve	Around 50 hours (± 10%)
Baseplate and Bridges	Microblasted grade 5 titanium with grey electroplasma treatment lends great rigidity to the baseplate, as well as the precise surface flatness essential to perfect functioning of the gear train. Bridges are also in grade 5 titanium, microblasted and black electroplasma treated.
Function Indicator	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).
Date Display	Semi-instantaneous, placed in a vertical aperture at 5 o’clock.
Balance	The free-sprung balance offers better reliability in the event of shocks, movement assembly or disassembly, and also guarantees 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	Platinum - By using a platinum rotor with the OneWay® winding system and ceramic ball bearings, the barrel can be efficiently wound while maintaining the compact dimensions of this extra-flat, skeletonised movement.
Case	Titanium - The inimitable tonneau shape was first imagined in an extra-flat form for the RM 67-01 case, making it one of the sleekest tonneau-shaped Richard Mille timepieces there is.
Case Dimensions	38.7 x 47.52 x 7.75mm
Dial	Skeleton - 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.
Water Resistance	50 m
Bracelets Material	Rubber
Finishing	Movement Microblasted anglage Microblasted milled sections Microblasted sinks Grey and black electroplasma treatment for the baseplate, hand-drawn after treatment
	Steel parts Lapped and polished ends Burnished pivots Post faces polished Hand-polished bevelling Hand-polished locking section
	Wheels Concave chamfering with a diamond tool Diamond-polished angles Circular-finished faces Rhodium plating (before cutting the teeth) Minimal corrections applied to the wheels in order to preserve geometry and performance.
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)
Other Features	Fast-Rotating Barrel (5 hours per revolution instead of 7.5 hours) - This type of barrel provides the following advantages: The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance, Provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio. Spline screws in grade 5 titanium for the bridges and case - This permits better control of torque applied to screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well. Gear-teeth profile - The entire going train of the watch, the primary transmitter of power to the movement, utilises a special profile for the teeth of the wheels. The wheels use a 20° pressure angle. This system equalises any discrepancies that might arise between the centres of each wheel, for instance during thermal changes and normal use, and promotes an excellent transmission of torque to the balance wheel, thus supporting superior chronometric results.
