Richard Mille Rm 67-01 Self-winding Slim Watch Technical Specifications

In the footsteps of never-ending creation, Richard Mille finally ushered in the birth of a new design, and is destined to become another future classic: the RM 67-01 ultra-thin watch.

CRMA6 movement: automatic winding skeleton movement, hour, minute, date display and function indicator.
Dimensions: 38.70 x 47.52 x 7.75 mm
The main function
Power reserve
About 50 hours (± 10%)
Tier 5 titanium base plate and bridge
The five-level titanium alloy material processed by micro-blasting and gray plasma plating has improved the rigidity and surface flatness of the movement’s bottom plate, which is a necessary condition for the perfect operation of the gear transmission. The bridge is also made of grade five titanium alloy material, which has undergone micro-blasting and black plasma plating for the first time in Richard Mille watches. Both the hollow base plate and the bridge plate have undergone independent and extensive verification tests to ensure their optimal strength requirements.
Date display
Half jump, shown by a vertical window at five o’clock.
Function indicator
The principle is similar to that of a car’s transmission. When the crown is pulled out, you can see the winding, date setting or manual setting position through the function indicator. The currently selected function is indicated by the hands at two o’clock: W (winding), D (date) and H (manual setting).

Variable inertia balance without balance spring
Can effectively improve the reliability of the watch when subjected to vibration and movement disassembly, and ensure more accurate movement time for a long time. Cancel the fast and slow needle fine-tuning system. By 4 small adjustable weights directly mounted on the balance wheel, the inertia of the balance wheel movement can be adjusted stably and finely.

The case of this classic watch symbolizes the first time that the barrel type is super-thin in the series, which is the most fashionable style in Richard Mille’s barrel timepieces. Compared with other similar cases in the series, its delicate dimensions require more time to build. The pure machining time has accumulated about six hours, and it does not matter the 68 different stamping processes required for the bezel, main case and bottom ring. Weeks of work. The processing of the bezel requires 8 days to complete the debugging of the machine, and the main case and the bottom ring each require 5 days of debugging. Before entering the real processing stage, the design of working methods for complex procedures took 145 hours, drawing auxiliary tool drawings took 130 hours, and assistive device manufacturing took 180 hours. Each case has to go through more than 215 independent processing procedures.
After completing its mechanical processing stage, each watch will be polished and polished, all hand-refined, and then assembled with sapphire crystal and sealant to undergo a preliminary water resistance test before being disassembled and Accept final quality control. Only after that can the movement be installed in its delicate lines. All these processes took another 8 man-hours, making the Richard Mille barrel case one of the most time-consuming and complicated cases in Swiss-made cases today.
Case with five grade titanium alloy spline screws
It is easier to grasp the tightening torque acting on the screws during assembly. Therefore, the screws can withstand the disassembly and assembly process, and are less prone to wear and aging.
Upper flange
Made of carbon fiber, the hour marker dots are filled with qualified luminous material.
