CHPTR_Δ is the first BA111OD manufacture watch complication: a unique timepiece that represents time in a revolutionary way. 

Rather than simply rotating a hand around a central axis, the movement was designed to "roll" a satellite hour wheel around a fixed central hour wheel. When a wheel is rotated around another wheel, the trajectory described by any point on this satellite wheel is a cycloid. There are several types of cycloids: in this BA111OD chapter, the chosen cycloid is a deltoid (with a ratio of 1/3), and as a result, the trajectory described by the tip of the hour hand is... a triangle.

Created with the help of renowned watchmaker Olivier Mory, CHPTR_Δ's asymmetrical reading of time is a world premiere that promises to captivate and inspire anyone who seeks a new and unique way of reading time.

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.

A connected glass

Together with all models of Chapter 4, all our CHPTR_Δ models include the NFC technology in their glass. A first in the industry!

Ba111od n’est pas compliqué (ou pas)

Ce qui est embarrassant chez Ba111od, c’est l’attente: entre la découverte sur le site, la commande, le paiement et la livraison, le temps s’écoule. C’est du temps compliqué, mais moins que la complication proposée. Complication inutile, mais ô combien élégante et originale! Alors dans cette attente, profitons de la Chapitre 3 et du tourbillon du Chapitre 4, attendons la Chapitre 5 et amusons nous avec une des dernières pièces nommées Chapitre 1. Ba111od est un livre ouvert qui se livre progressivement. Prenons notre temps pour attendre le temps. Ce n’est pas compliqué !
