One of the most dazzling watches of 2024 was undoubtedly the SpaceOne Tellurium. You could describe it as a wrist-worn planetarium that also tells the time. It comes from SpaceOne—a brand whose name already hints at the aesthetic direction of its collection. The talented duo behind SpaceOne, Guillaume Laidet and Théo Auffret, first surprised us in 2023 with a neo-futuristic Jumping Hour watch that looked like a miniature spaceship. The standout feature? It launched at just €1,900—unthinkably low for this category, where comparable pieces from other brands typically come with six-figure price tags. Unsurprisingly, all 500 pieces sold out instantly. Since then, the company has released several variations of the Jumping Hour, slightly raising the price—though even the most expensive version retails for just €2,850. You can find them here:
SpaceOne’s next major step came in 2024 with the launch of the Tellurium, the brainchild of French automotive designer Olivier Gamiette. In his spare time, Gamiette relaxes by designing watches with unconventional ways of displaying the time. From his remarkably creative mind came the idea of a wrist planetarium, one that depicts Earth’s annual orbit around the Sun—alongside the Moon.
Indeed, the SpaceOne Tellurium features a heliocentric planetary display combined with a jumping date and a rolling month indicator.
It’s worth seeing in action:
This is a proprietary, patented system produced entirely in-house at SpaceOne’s workshop, located inside the Paris atelier of independent watchmaker Théo Auffret. Auffret is known for his tourbillons and was awarded at the Grand Prix d’Horlogerie de Genève (GPHG) in 2022.
The Tellurium features a 42 mm titanium case with a shape that defies convention. It resembles a smooth, polished silver pebble, curved on both sides, sealed in vacuum under a sapphire crystal dome. Its dial is made of aventurine, a man-made stone that resembles a starry night sky. The watch has just two luminous hands—for hours and minutes—and only three hour markers: 12, 4, and 8, replacing the typical 3-6-9-12 configuration.
Until now, no watchmaker had dared to develop such an astronomical complication at such an accessible price point: just €2,999 (pre-tax). Unsurprisingly, the pictured version sold out instantly—as did the blue titanium edition. However, a black titanium version of the Tellurium is still available on the brand’s official website. Only 95 pieces remain, priced at €3,707.
The Tellurium’s distinctive design gives us a tantalizing glimpse of what SpaceOne might offer in the future. One thing is certain: this is a brand we’ll be following very closely.
