RICH RM 67-02 Carbon Case & Integrated Movement Explained
The RICH RM 67-02 focuses on two key areas of development: the construction of its layered carbon case and the design of its CRMA7-style integrated mechanical movement. Rather than relying on decorative movement plates, this version uses an integrated movement architecture where visible components form part of the mechanical system.RICH RM 67-02 Carbon Case & Integrated Movement ExplainedRICH RM 67-02 Carbon Case & Integrated Movement ExplainedRICH RM 67-02 Carbon Case & Integrated Movement ExplainedRICH RM 67-02 Carbon Case & Integrated Movement ExplainedRICH RM 67-02 Carbon Case & Integrated Movement Explained
This article explains the watch’s case construction, movement layout and skeletonized design based on the manufacturer’s published specifications.
Layered TPT-Style Carbon Case
The RM 67-02 uses a case made from layered TPT-style carbon material. Multiple thin carbon fiber layers are stacked before being compression-molded under controlled temperature and pressure.
After machining, the layered construction creates the characteristic wave-like carbon pattern. Because carbon fiber is naturally irregular, each case displays a unique surface texture.
According to the manufacturer, each case is individually molded before undergoing CNC machining, drilling, polishing and final assembly. The finished appearance depends on both the carbon material and the precision of the manufacturing process.
Three-Piece Case Construction
The watch features a three-piece case consisting of the front bezel, middle case and case back.
Besides the external profile, the case also includes several structural mounting points, including:
- Front and rear crystal installation
- Crown position
- Case screw locations
- Movement holder
- Internal movement mounting structure
Maintaining dimensional consistency between these components is important for proper assembly.
Front and Rear Sapphire Crystals
The RM 67-02 features transparent crystals on both sides, allowing the movement to be viewed from the front and back.
The front crystal highlights the skeletonized dial side, while the rear crystal provides a view of the automatic winding mechanism and additional movement components.
Proper crystal fit also contributes to the overall alignment of the case structure.
CRMA7-Style Integrated Mechanical Movement
The watch is equipped with a custom CRMA7-style integrated automatic mechanical movement.
According to the manufacturer, the movement measures approximately 3.99 mm in thickness.
Unlike decorative plate designs, an integrated movement is engineered so that the visible bridges, gear train and barrel are part of the functional mechanical architecture.
This allows the skeletonized appearance to reflect the movement’s actual structure rather than decorative components.
Integrated Movement Architecture
Many skeleton-style watches use decorative bridges or non-functional gears to create an open-worked appearance.
An integrated movement follows a different approach by designing the bridges, wheels and transmission system as part of the operating movement.
As a result, many visible mechanical components participate in the movement’s normal operation.
Barrel and Gear Train Layout
The manufacturer states that the barrel, ratchet wheel and front gear train have been repositioned and resized.
The barrel stores the mainspring energy, while the gear train transfers power throughout the movement.
Their placement influences both the mechanical layout and the visual balance of a skeletonized movement.
Skeletonized Construction
The RM 67-02 uses an open-worked bridge design to expose more of the internal mechanism.
The front side displays the barrel, bridges and gear train, while the reverse side reveals additional transmission components and the automatic winding system.
Some visible gears within the movement are part of the operating mechanism, creating a layered mechanical appearance from both sides of the watch.
Bridge Design
Movement bridges serve two primary purposes: supporting gears and maintaining structural rigidity.
Reducing unnecessary bridge material increases movement visibility while preserving mechanical strength.
Bridge geometry, mounting points and cut-out sections all contribute to the final appearance of the movement.
Crown, Case Screws and Movement Holder
According to the published specifications, this version also includes revised dimensions for the crown assembly, case screws and internal movement holder.
These components help secure the movement inside the case while maintaining proper alignment during assembly.
Compatibility Information
The manufacturer indicates that several structural components are produced according to dimensions intended to match the original design, including the case structure, crown, crystals and internal mounting system.
Actual compatibility may vary depending on manufacturing tolerances, production batches and component condition. Practical fitting should always be confirmed through physical inspection rather than relying solely on published specifications.
Overall Design
The RICH RM 67-02 combines a layered carbon case, an ultra-thin integrated mechanical movement and an open-worked architecture into a unified design.
Its primary engineering focus lies in coordinating the case structure, movement thickness, gear layout and skeletonized construction while maintaining the slim profile associated with the RM 67-02 design.
As with any mechanical watch, overall assembly quality, movement performance and long-term reliability should be evaluated through inspection and functional testing.
