Neuchâtel, March 2023 – The young brand BA111OD is very proud to launch during the watch fairs in Geneva its first manufacture complication, which brings an unprecedented reading 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.

The brand’s founder, Thomas Baillod, is proud to present BA111OD’s first manufacture complication. While the minute hand travels around the dial in the usual way, the hour is indicated by a small dot following a hypocycloidal path within a triangle, creating a non-linear experience of time. "I particularly appreciate this aspect. Besides being mesmerizing, it's the symbolic aspect of life that fascinates me. Like those precious moments that last or slip away... the hour dot slows down and then speeds up again in a movement that appears irregular yet is perfectly calibrated and precise."

A hypocycloidal reading of time

This project, initially imagined by the designer Diego Böttger-Zevallos, turns out to be complex to realize. Thomas Baillod takes on the challenge. To ensure its technical development and production, he once again calls upon the brilliant watchmaker Olivier Mory, who is already responsible for the paternity of the BA111OD Chapter 4 Tourbillon. "There is hardly anything but the transcendent beauty of mathematics to obtain a triangle using only things that rotate in circles! And it is a discreet tribute to the several centuries-old use of the cycloid in watchmaking. Galileo, Newton, Huygens, Euler, Cantor or Roberval, to name but a handful, have all worked on the amazing properties of these curves," says Olivier Mory.
