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 blue execution, this version brings a more vibrant and expressive dimension to the concept, highlighting its architectural design, depth and distinctive identity.

NON-CIRCULAR EXPERIENCE OF TIME

Developed and produced with the help of the highly renowned watchmaker from La Chaux-de-Fonds, Olivier Mory, CHPTR_Δ (pronounced Chapter Delta) brings a duality between the circular time of the minutes and the hypocycloidal time of the hours, enclosed in a triangle, in the foreground of the dial. This asymmetrical reading of time, which slows down and starts again, like a choreography, is part of another temporality, symbolizing the carousel of life.
