Christophe Claret


Maestoso’s high-precision regulator follows in the wake of 18th century marine chronometers. These antique timepieces featured incredibly accurate pivoted detent escapements that enabled the calculation of longitude for safe navigation at sea. Maestoso breathes new life into this historical regulator by optimising its design and functionality specifically for the wristwatch.


Charles X, King of France, was an important influence on decorative arts in the 19th century and inspired the aesthetics of pocket watches of the era. Christophe Claret has managed to translate Charles X's architectural approach with Maestoso’s stepped bridges, creating a symbolic connection between design and tradition.

Maestoso has written a new chapter in the history of Haute Horlogerie. And the challenge? To equip a wristwatch with a traditional detent escapement, a mechanism usually designed to run in a perfectly stabilized position, and which, thanks to its sublime beauty, manages to eclipse the tourbillon.

Enabling the mechanism to operate in all the positions that wearing a wristwatch entails – without resorting to the convenience of a modern, shorter detent – is a genuine gamble, pulled off via the three patents and a series of additional innovative systems. To prevent the detent from turning over, an anti-pivot cam, integral to the spring balance, works in conjunction with the safety finger. To cope with the risks of over-banking, a flexible thrust bearing fitted on the wheel and connected to the balance absorbs any excess energy.

Christophe Claret has also endowed the watch with a constant force, guaranteeing stable energy and amplitude throughout the power reserve.
