Introducing the Celestial Tourbillon Collection, the first chapter of Atelier Loreti, the high-end sister brand of Filippo Loreti. Created to explore the upper limits of design, craftsmanship, and mechanical artistry, Atelier Loreti is built on a clear mission: to make high horology more accessible without compromising authenticity, precision, or design.

At the heart of this collection lies one of watchmaking’s most prestigious complications: the tourbillon. Developed over three years, the mission behind our L.1T caliber was clear: to translate the pinnacle of horological complexity into a durable, accessible masterpiece. Built on a modified Japanese automatic architecture derived from the Miyota 8215 movement, it balances artisanal finish with everyday reliability, marking a new step in Loreti’s vision to democratize high-end watchmaking and open the world of mechanical excellence to a new generation of collectors.

Each timepiece is defined by its minimalist design and the use of exceptional dial materials. Natural semi-precious stones and celestial materials, from Black Onyx and Blue Aventurine to Turquoise and Meteorite, bring depth, texture, and individuality to every watch. No two dials are ever the same, making each piece a unique expression of both nature and mechanical art.

The Celestial Tourbillon Collection embodies a new vision of watchmaking, where rare materials, refined aesthetics, and one of horology’s most complex complications come together in timepieces designed to be worn, experienced, and owned.

THE L1T TOURBILLON

At the heart of the Celestial Tourbillon lies the L.1T caliber, a reengineered automatic movement developed over three years to make one of watchmaking’s most prestigious complications more accessible. Built on a modified Japanese automatic architecture derived from the Miyota 8215 movement, it was extensively reworked into an authentic 4Hz Tourbillon beating at 28,800 vph. Composed of over 200 components, it rotates continuously at 6 o’clock, combining mechanical artistry with everyday wearability and lasting reliability.

OPEN CASEBACK

An open caseback reveals the structure of the L1T caliber, where refined finishes, a sculpted rotor, and engraved details including the Celestial Tourbillon name and Atelier Loreti signature bring mechanical precision to life. Individually numbered as part of a limited edition of 300 pieces, each watch holds its place within the series. A clear view into the heart of the watch, where precision is fully revealed.

BLACK ONYX

Black Onyx, the most iconic variety of agate, is a naturally occurring stone known for its deep, uniform black surface. Revered for centuries in art and craftsmanship, it appears carved from pure darkness. Its polished finish absorbs light completely, allowing the exposed Tourbillon to appear suspended in a void with no beginning and no end. Mirror-like in depth, the stone brings strength, focus, protection, and a refined intensity to this masterpiece.

DESIGNED TO BE WORN

High horology, shaped for everyday wear. With a refined 42 mm case and a slim 10.85 mm profile, the Celestial Tourbillon balances mechanical presence with elegant proportions. Finished with a supple black leather strap, it sits naturally on the wrist while keeping the tourbillon and meteorite dial at the center of attention.

TIME, CARVED IN BLACK

Deep black onyx creates a pure, polished backdrop for the L.1T tourbillon. Its absolute darkness draws the eye to every movement of the mechanism. A meeting of natural stone, refined design, and mechanical artistry.
