The Richard Mille series stands out, not relying on a single watch, but has created several new works in a short time, and is recognized by collectors and industry experts as the ultimate classic of contemporary watchmaking. The most popular classic model is the RM 010 automatic winding watch. Its pure lines and functions can always resonate with customers. Following the non-stop creative steps, Richard Mille finally ushered in the birth of a new design, and is destined to become another future classic: RM 67-01 automatic refining ultra-thin watch.
Creating the mechanical aspects of ultra-thin automatic watches has its own set of special difficulties. However, one of the double challenges is to combine this type of movement design with the deep visual layering in the movement. This is the core principle of Richard Mille’s creation. . This spirit is extremely evident in the intensive hollowing out of RM 67-01. However, the new method of dial construction, from the edge of the three-layer bezel to the hour and minute hands in the central area, is also dizzying.
The figures of the new model are forged from solid metal and mounted on a pair of solid titanium alloy tracks connected directly to the movement. In order to increase the sense of depth, each number is engraved with solid metal and filled with Luminova® luminous material to facilitate night reading. This is an innovation of the brand in this watch category. This time, the vertical date window was moved to the five o’clock position on the right side of the dial, and the hidden window frame was also highlighted with Luminova® luminous material.
The CRMA6 automatic winding movement for the RM 67-01 watch is a new movement with a thickness of only 3.6 mm, designed by Les Breuleux engineers. The bottom plate and bridge plate of the movement are made of grade five titanium alloy, combined with gray and black plasma treatment as a precision modification, with platinum automatic disc pendulum. The bottom cover of the movement continues to create a deep sense of extra care, and large-scale hollowing effects are everywhere, such as highly hollowed upper barrels, automatic disks, drive trains and automatic winding devices. The building structure of the movement is enough to load the mechanical legend; even the three slotted screws on the dial side are a metaphor for the spirit of the watchmaker’s anti-traditional approach, and the extensive use of custom torque screws Use to ensure that it is accurately and appropriately applied according to the correct tension of function and use.
The core of the structure design of the movement lies in the use of involute teeth in the entire transmission wheel system, instead of the standard cycloid teeth commonly used in watchmaking. This tooth profile is found in automotive transmissions and many high-efficiency electric motors; however, their use in the field of watchmaking is rare. This tooth profile makes the energy transfer through the drive wheel system more efficient, and therefore results in superior timing results.
Winding, date and manual adjustment indicators are displayed between one and two o’clock. Although this is a new automatic timepiece, it still needs to be slightly polished when worn for the first time or after several days without wearing. When the crown is pulled out, the indicator starts to run, so using the crown’s forward and backward position, you can simply select or touch the function by touching or ‘clicking’ on the number.
The case of this classic watch showcases a barrel shape in the series. For the first time, it is interpreted in an ultra-thin form, which is the most fashionable style in Richard Mille barrel-type timepieces.
Compared with other similar cases in the series, its delicate size requires more time to build. The pure processing time has accumulated about six hours, and the preliminary preparations such as 68 different stamping processes required for the bezel, main case and bottom ring are required. For weeks. 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 processing phase, each watch will be ground 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 Cask-shaped case one of the most time-consuming and complicated cases in Swiss-made cases today.
