The SpaceOne Tellurium blends the beauty of celestial mechanics with exceptional watchmaking craftsmanship. Developed in-house by Théo Auffret and designed in collaboration with Olivier Gamiette, the Tellurium is a poetic and mechanical tribute to Earth's journey through space—now reimagined in a striking new limited edition.

Housed in a Grade 5 titanium case with a unique blue treatment, the 42mm case combines polished, brushed, and sandblasted finishes for a dynamic, sculptural effect. The aventurine dial evokes a star-filled night sky, enhanced with polished titanium stars and PVD-treated titanium apertures for the date and month indications.

At its heart, the Tellurium is powered by a Swiss automatic Soprod P024 movement, augmented with SpaceOne’s patented heliocentric complication module. This mechanical marvel displays the hours, minutes, date, and month, while also tracking the real-time positions of the Earth and Moon in orbit around the Sun—accurately for over a century. Adjustment is intuitive, requiring only a standard crown correction for months with fewer than 31 days.

Each Tellurium is meticulously assembled in Paris through 65 separate operations, involving 37 complication components and 18 casing elements. A rigorous 48-hour testing phase ensures precision and water resistance up to 30 meters.

Limited to just 200 pieces, the Tellurium Blue Titanium is delivered air-sealed in a bespoke aluminum pouch and presented in the signature SpaceOne watch roll, inspired by astronaut gear and space-travel technology.

A vision of Earth’s celestial journey—captured on the wrist.
