Description

BA111OD unveils CHPTR_Δ, the brand's first horological complication, made in Switzerland, that revolutionizes the representation of time.

This timepiece, far from traditional designs, features an innovative mechanism: a satellite hour wheel "rolls" around a fixed central wheel, breaking away from the classic movement of a hand around a central axis. This dynamic draws a cycloidal trajectory.

In this unprecedented model, BA111OD has chosen a deltoid cycloid with a 1/3 ratio, thus making the hour hand trace a distinctly triangular path. This innovative display of time, a first in the watch industry, promises to enchant those seeking a new and unique approach to time reading.

Born out of a collaboration with the renowned watchmaker Olivier Mory, CHPTR_Δ is an ode to innovation and uniqueness in the realm of contemporary horology.
