In the autumn of 2025, celebrating a decade of Emmanuel Bouchet Complication One, it now comes in three materials: Aleph in gold, Contrast in titanium and gold, and for the first time: Complication One Fusion with a sapphire case. These 44-millimetre cases, second to diamonds in hardness, are extremely complex to make, and require hundreds of hours of machining and hand polishing – especially when reproducing the elegantly curved case sides known from the metallic models.
The sapphire-cased Fusion has a mix of sapphire and titanium subdials. The Complication One Fusion is a limited edition of 5 pieces.
