The base of this special custom design is a movement by Christophe Claret: a minute repeater on two gongs that carries the caliber name CLA 88. The client’s wish was a modification to the dial so that it would become a 24-hour display. The artistic implementation of the day/night disk is reminiscent of an oil painting.

THE REVOLVING PAINTING

The Night & Day, a wristwatch with exceptional time display and sound. This custom realization from the Aurum line is striking in one particular element that emphasizes the artistic skill of Grieb & Benzinger: the 24-hour revolving day/night display especially designed for this project was painted by hand after being previously engraved in a cartoon style. The color gradients between day and night are like those of an oil painting, which at first seemed technically impossible given the materials and colors. The weight of the disk as well as the amount of paint applied had to be adjusted to the power of the movement’s drive in order to guarantee precision. The chiming as well as a minimalist hour-and-minute display top this watch off.
