CHPTR_Δ [AGIL] Club 11:10 Limited Edition

Created as the first timepiece reserved for Club 11:10, this 40mm limited edition reflects BA111OD’s commitment to independent watchmaking rooted in Neuchâtel and shaped in close dialogue with its community.

CHPTR_Δ (Delta) is the first manufacture complication developed by BA111OD in Neuchâtel, conceived to challenge traditional ways of reading time. Instead of a conventional rotating hand, the movement features a satellite hour wheel rolling around a fixed central hour wheel.

This motion follows a deltoid cycloid with a 1:3 ratio, causing the tip of the hour hand to trace a perfect triangle. Time is no longer displayed in circles, but through a constantly evolving geometric form inspired by mechanical logic and mathematical precision.

Developed in collaboration with independent watchmaker Olivier Mory, CHPTR_Δ introduces an asymmetrical reading of time and marks a world premiere.

Presented in a 40 mm case and limited to 30 pieces, this edition is reserved exclusively for Club 11:10 members. A bold expression of Neuchâtel’s independent spirit, designed for collectors who choose to experience time differently.
