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.

Lieferung mit Schwierigkeiten

Nach über 1 Jahr und mehrerer Probleme bei der Lieferung (dauerte 8 Tage!!!) habe ich endlich die Uhr am Arm. Sie sieht sehr schön aus. Über die Funktionlität kann ich noch nicht viel sagen. Aber die mittelmässige Bewertung liegt hauptsächlich an der fürchterlichen Auslieferung.

Beautiful Time Piece ❤️

The CHPTR_Δ.2 B.ROK is exceptionally beautiful, perfect weight, the 44mm not too large (on 8" wrist), the silicon bracelet is super comfortable, the clasp is very unique, the domed sapphire crystal illuminates the dial and complexities. The 4 o'clock (red/black) date window is subtle yet accessible and perfectly centered. The Hour red lollipop paddle is absolutely precise. The Minute hand glows (a little) in darkness; this is NOT a dive watch. Everyone notices a Special Time Piece on my wrist and asks questions. Fantastic Design and Execution... absolutely worth the price. You will not be disappointed.
