spaceone’s titanium tellurium watch replicates the earth and moon’s orbit around the sun

SpaceOne designs Tellurium like the solar system

SpaceOne unveils Tellurium, a watch made of Grade 5 titanium that replicates the orbit of the Earth and Moon around the sun on its dial. It has two polished titanium spheres; the larger one represents the Earth, while the smaller one attached to it for the Moon. They orbit around the ionic plate, colored deep blue to recall the hue of space.

At the stroke of midnight, the calendar at the 6 o’clock position of the watch gears up its mechanism, making the numbers slide with a soft tick to display the new date. The Tellurium’s mechanism design is by Theo Auffret, its case and dial by Olivier Gamiette, and SpaceOne collaborates with the Auffret Paris Workshop in developing the watch.

Mimicking celestial bodies’ movement in titanium watch

SpaceOne’s titanium Tellurium watch can also predict when the next full moon occurs, given that a whole piece of its design is inspired by the movement of the celestial bodies. A mechanism named Soprod P024 Movement makes it possible for the titanium watch to mimic the Earth and Moon orbiting the sun, and these spheres on the dial even represent the real rhythm of their counterparts. The Earth orbits the sun in 1 year, and the Moon orbits the Earth in 27.3 days, completing a full lunar cycle in 29.5 days, thus following their real rhythms in the Tellurium watch.

Inside SpaceOne’s titanium Tellurium watch, there’s a part called the star wheel which has 31 teeth that move the date. This wheel also moves two smaller star wheels, each with 12 teeth. One of these smaller wheels changes the months, and the other is for the Tellurium complication. The planets on the watch are attached to a piece of sapphire crystal, which is connected to another ring but has 365 teeth.

This represents the number of days it takes for the Earth to orbit around the sun. Then, the Moon is connected to a small gear, which is fixed to another part of the watch. The wearer can see this from the outside of the watch and can adjust the Moon’s position using a quick date function. They may also need to fine-tune it depending on the number of days in the month, either 30 or 31.

Replacing hours with just three numbers

SpaceOne’s design team has cleared the titanium watch’s dial of unnecessary details. Tellurium focuses only on having two hands that show the hours and minutes, both of which glow in the dark like spaceships in the universe. The hands for hours and minutes, made of aventurine, are at the center, just like the sun in the middle of the galaxy. Instead of the usual hours (3, 6, 9, 12), SpaceOne’s titanium Tellurium has only three numbers: 4, 8, and 12.

These numbers form a triangle around the center of the dial, mimicking the other planets that rotate around the Sun. With these, SpaceOne hopes the wearer sets their eyes more on the way the titanium watch is designed, which harks back to the movement taking place in the solar system. As of publishing this story, SpaceOne’s titanium Tellurium is set to begin delivery starting October or November 2024, with each timepiece currently priced at 2,990 EUR.
