Orient Star RE-BZ0005G00B M34 F8 Avant-Garde Skeleton – Limited Edition
 
The Orient Star RE-BZ0005G00B is one of the most technically advanced models in the M34 collection, combining bold, contemporary design with high-end Japanese mechanical engineering. Produced as a limited edition of just 300 pieces worldwide, this Avant-Garde Skeleton model is designed for enthusiasts who appreciate both mechanical complexity and modern aesthetics.
 
With its openworked dial, in-house F8 movement, and architectural design, this watch offers a completely different experience compared to traditional mechanical watches.
 
Avant-Garde Skeleton Dial – Mechanical Depth on Display
The RE-BZ0005G00B features a fully openworked (skeleton) dial, designed to showcase the movement from both the front and back.
Skeletonised dial with multi-layer construction
Small seconds sub-dial
Power reserve indicator
Date display
Visible gear train and mechanical components
Unlike standard open-heart designs, this model exposes a much larger portion of the movement, creating a bold, technical look.
 
Advanced Dial & Skeleton Construction
This model uses a dual-layer openwork structure, engineered for both aesthetics and structural integrity.
The process includes:
Precision cutting of the upper dial layer to create the skeletonised openings
A secondary structural layer that maintains rigidity while allowing visibility of the movement
Careful finishing of exposed components to ensure a clean, high-end appearance
Integration of visible movement elements, including the partially skeletonised base plate and silicon escape wheel
This construction gives the watch a three-dimensional, architectural feel, setting it apart from more traditional skeleton designs.
