Engineered in Motion
THE L1T
TOURBILLON
At the heart of the Celestial Tourbillon lies the L1T caliber, a reengineered automatic movement. Composed of over 200 components working in harmony, the tourbillon rotates continuously at 6 o'clock, turning the dial into a living stage of mechanical art. Based on the Miyota 8215 architecture and refined for performance and reliability, this movement combines technical mastery with everyday wearability. Developed over more than three years, it is engineered for lasting reliability, durability, and precision.

The Celestial Tourbillon by Atelier Loreti
The Celestial Tourbillon is the watch of Atelier Loreti, the high-end line of Filippo Loreti. Its tourbillon sits at 6 o'clock on the dial: the balance wheel, pallet fork and escape wheel turn inside a cage that makes one full rotation every minute.
The L.1T calibre
The L.1T is an automatic tourbillon calibre developed over three years. It is built on an automatic architecture derived from the Japanese Miyota 8215 and reworked to carry a true tourbillon, beating at 4 Hz (28,800 vibrations per hour) with more than 200 components. A rotor winds the mainspring as you wear the watch.
The dials
Each reference has a natural material on the dial: Meteorite, cut from an iron meteorite with its own Widmanstatten pattern, Black Onyx, Blue Aventurine and Turquoise. Because the materials are natural, no two dials are exactly alike. The case is 42 mm in stainless steel, 10.85 mm thick, under sapphire crystal.
