A tribute to one of haute horlogerie's most iconic skeletonised chronographs.

Why This Piece

The Big Bang Unico silhouette is one of the most recognisable in modern watchmaking — bold, architectural, and unapologetically avant-garde. This homage captures that same energy: the skeleton dial, the integrated rubber strap, the tonneau-influenced case, and the exhibition caseback that puts the movement on full display. For the collector who appreciates the aesthetic without the six-figure price tag, this is the definitive entry point.
