The genesis of the Secret edition
The Secret Edition was the original vision of Gautier Massonneau, Founder and Creative Director of the Maison. Its technical complexity, however, required two years of research and development to bring this intimate and poetic customization to life.
The celestial coordonates of the stars
Each star has a unique position in the sky, defined by its celestial coordinates. However, their apparent position evolves over time due to the Earth’s movement around the Sun and the tilt of its axis. The algorithm used incorporates these variations to calculate the exact position of the stars at a specific moment in your personal history.
A first in watchmaking
The precise position of the stars is calculated using an algorithm that integrates more than 1,600 constellations. This system is based on the work of Belgian astronomer Jean Meeus, an international reference in astronomical calculations. *
*His work can be found in the book “Astronomical Algorithms” (Jean Meeus, Société Astronomique de France, Paris, 1986).

Our in-house movement, the X-Nihilo
The Secret edition is powered by the X-Nihilo calibre, the Maison’s first in-house movement. From design to assembly, every step takes place in Paris, within the Trilobe Manufacture, where micro-precision excellence meets watchmaking expertise.
Discover the X-Nihilo calibre:

Crafting the starry sky
The sky is brought to life on the dial by the skilled hands of an artisan mastering the horological art of decal application. Each constellation is first engraved on a metal plate, then meticulously transferred onto the dial using a pad-printing technique. The artisan applies a powdered silver ink in successive micro-deposits, with a perfectly controlled gesture.
Each star gradually emerges, layer by layer, achieving a delicate balance between brilliance, density, and refinement. This patient process gives the stars subtle relief, while the lacquer work adds depth, creating the illusion of celestial bodies floating above the dial, suspended in the vastness of the night sky.
Produced in a clean room to preserve the purity of the dial, this meticulous craftsmanship requires absolute precision. Each piece becomes the expression of rare expertise, where technical mastery meets the poetry of the sky.
A new interpretation
The Trente-Deux Secret edition is also available in a rose gold case paired with a rubber strap, carefully matched to the hue of the sunray dial. The combination of rubber and rose gold enhances the versatility of the collection, creating a unique balance for a relaxed, everyday look while preserving the sophisticated aesthetic that defines the Trente-Deux.

Present the watch to your clients

A unique piece
Each starry sky dial is custom-made through transfer of the stars and corresponds to a moment (day, time and place) dear to the client.
A piece filled with emotion
The client gives us a day, a time, a place, corresponding to a precious moment of its life (a wedding, a birth, an adventure…). We take a picture of the starry sky corresponding to this special moment et we engrave it on the watch. Thus, the watch tells the client’s story. The Secret watch is a subtle way to free time, from a happy or promising moment, and to freeze it for eternity.
An innovating piece
We determine the position of the stars through an algorithm of 1600 constellations, around a repetitive 4-year cycle. This algorithm is base on the book “Calculs astronomiques à l’usage des amateurs” (Jean Meeus, Société astronomique de France, Paris, 1986). Thus, we are capable to determine the sky of a moment in the past but also in the future… which is ideal for a wedding watch for example. Each star linked to a constellation is manually filled with superluminova by a craftsman These light up after being exposed to a UV light, and come to life in order to illuminate the chosen moment, thus suspending the passage of time. Due to the technical complexity of the dial, 2 years of R&D were necessary to conceive the Secret watch.
