Black Skeleton Tellurium

Most calendar watches tell you the date. This one also tells you where the Earth is. At the centre sits the Sun, with the Earth and Moon keeping their places around it on SpaceOne's patented heliocentric module. Limited to 70 pieces.

Théo Auffret designed the module, which is assembled in France. Each time the date turns, the month moves on and the Earth takes one step along its orbit; SpaceOne says the positions hold for more than a century. The only chore is the one any date watch asks: a correction after a short month.

Everything here is dark: black DLC on the Grade 5 titanium case, and a black aventurine centre with polished titanium stars under a domed sapphire. Inside is a Soprod P024 H4 automatic with a 38-hour power reserve. 42 mm across, 16 mm thick, water resistant to 30 m, on a black fabric strap.
