Orient Star RE-BZ0004B00B M34 F8 Avant-Garde Skeleton – Black
 
The Orient Star RE-BZ0004B00B is a bold, technically driven model from the M34 Avant-Garde Skeleton collection, combining modern design with high-performance Japanese watchmaking. Featuring a black IP-coated case, multi-layer skeleton dial, and advanced in-house movement, this model delivers a strong, architectural presence on the wrist.
 
Designed for enthusiasts who want something more contemporary and mechanical, it showcases the movement as a core part of the design rather than hiding it behind a traditional dial.
 
Avant-Garde Skeleton Dial – Engineered Depth
The RE-BZ0004B00B features a fully skeletonised, multi-layer dial, designed to create depth and expose key mechanical components.
Openworked dial with layered construction
Power reserve indicator
Small seconds display
Visible gear train and movement architecture
The dial is designed to feel structural and three-dimensional, with different layers interacting under light to create a constantly changing look.
 
Advanced Skeleton Construction
This model uses a dual-layer dial and movement integration, where the dial is built around the movement rather than placed on top of it.
The construction includes:
A precision-cut upper dial plate with applied indices
A lower structural layer for rigidity and alignment
Integration of exposed components to create a seamless mechanical display
A partially openworked movement revealing key elements including the escapement
This results in a technical, architectural aesthetic, setting it apart from traditional skeleton watches.
