BA111OD - CHPTR_Δ.7 [ELLA] BLACK DIAMOND 40 mm (leather)

Description

Take advantage of the Special Launch Offer by ordering the leather version and receiving a complimentary black rubber strap. Thanks to the easy-clip system, you can effortlessly switch between the two styles yourself.

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

The CHPTR_Δ.7 [ELLA] Black Diamond is distinguished by its sophisticated anthracite hue. The meticulously crafted details give this piece a touch of discreet luxury within timeless elegance.

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.
