Your unique piece
One day, one time, one place. Three markers that tell the story of a moment in life: a meeting, a birth, a promise, an achievement. Each dial is custom-made and recreates, through the printing of stars, the sky at a chosen moment, past or future, at a specific place, date, and time. Each Secret watch is therefore unique, imbued with meaning and emotion. A reflection of your story, whose secret is known only to you.

MY SOUL HAS ITS SECRET, MY WATCH HAS ITS STORY.
An Algorithm
A Sky

A MOMENT
Each star has a unique position in the sky, defined by its celestial coordinates. However, its apparent position changes over time due to the Earth’s movement around the Sun and the tilt of its axis.
AN ALGORITHM
The precise position of the celestial bodies is calculated using an algorithm incorporating more than 1,600 constellations. It is based on the work of Belgian astronomer Jean Meeus, an internationally recognized authority in astronomical calculations.
His work is available in his book Astronomical Algorithms for Amateurs (Jean Meeus, Société astronomique de France, Paris, 1986).

A Sky
Each constellation is first engraved onto a metal plate, then meticulously transferred onto the dial using a pad-printing technique. The artisan picks up a powdered silver ink, applying it to the dial through successive micro-deposits, with a perfectly controlled gesture. Each star is thus revealed, layer by layer, until achieving the subtle balance between brilliance, density, and delicacy.
This patient process gives the stars a slight relief, while the lacquer work adds subtle depth, making the celestial bodies appear to float above the dial, as if suspended in the vastness of the night sky. Carried out in a cleanroom to preserve the purity of the dial, this work of exceptional craftsmanship requires absolute dexterity. Each piece thus becomes an expression of rare savoir-faire, where the precision of the artisan’s hand meets the poetry of the sky.
A Luxury for Oneself
The Genesis of the Secret Edition
The Secret edition was the original project of Gautier Massonneau, Founder and Creative Director of the Maison. However, its technical complexity required two years of research and development to bring this intimate and poetic form of personalization to life.
