CHPTR_Δ.2 [B.ROK]

CHPTR_Δ (Chapter Delta) is the first BA111OD manufacture watch complication, a unique timepiece that represents time in a revolutionary way. Developed with renowned watchmaker Olivier Mory, it introduces an entirely new approach to time display. Instead of simply rotating a hand around a central axis, the movement was conceived to roll a satellite hour wheel around a fixed central hour wheel. This creates a deltoid trajectory, meaning the tip of the hour hand traces a triangle, a world premiere in watchmaking. With its asymmetrical reading of time, CHPTR_Δ challenges convention and offers a bold new way to experience horology. Presented here in a black execution, this version reveals the most graphic and assertive expression of the concept, highlighting its architectural design, depth and singular identity.   List of compatible watchbands : Bracelets – BA111OD
