Unique composite materials for exceptional timepieces
At the EPHJ 2026 trade show, Composites Busch explores an ultimate symbol: Gold.
A starting point, like an invitation to push the boundaries of the material, to reconsider it, to reinterpret it, and to reveal its unexpected expressions.
A universal benchmark of value, rarity, and status, gold holds a foundational place in watchmaking heritage.
At Composites Busch, it becomes a testing ground, a source of new expression, at the crossroads of tradition and innovation.
Our developments for this edition incorporate gold in the form of sheets, combined with a matrix of mineral fibers, all bound together by a bio-based resin. This architecture gives rise to a material that is stable, durable, and controlled, embodying a unique aesthetic.

“Beyond performance, each material is conceived as a signature”
In a subtle balance between craftsmanship and high technology, our approach is based on listening, understanding, and co-development with the Houses.
It is through this exchange that bespoke solutions are born solutions that cannot be standardized, designed to reveal the unique identity of each creation.
At the intersection of craftsmanship and materials engineering, Composites Busch asserts itself as a creative partner, dedicated to bringing into being what does not yet exist.
