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.

Très belle montre.

J'adore le design de cette montre.

J'ai constaté que la boule bleu a du jeu, quand je bouge légèrement la montre, la boule se déplace de quelques dixièmes de millimètre.

Par contre, je suis déçu de la qualité du balancier qui a plusieurs défauts d'usinage (fissures, creux).

Une belle réussite!

J'adore le concept et l'esthétique de la montre. Je regrette juste que la boule bleue de l'aiguille des heures n'est pas aussi présente que sur les dessins 3D et que le fond triangulaire du mouvement ne soit pas noir comme indiqué. Pour le reste c'est un bel objet. Merci et bravo.

Great Masterpiece

The watch is beautiful and fascinating. You need to learn how to read it but then it is a pleasure to observe the hours progressing.
It is an eye catcher and a great gadget for a watch lover/maniac.
Everyone who looks for the special one should have such a masterpiece.
