CVDK Grand Planetarium Eccentric Silicium

CVDK × Revolution Grand Planetarium Eccentric Silicium, limited to six pieces and based on a model first introduced in 2024 to mark the 50th anniversary of CVDK. The Grand Planetarium Eccentric is the first and only mechanical wristwatch capable of displaying the real-time orbits of all eight planets in our Solar System, from Mercury all the way out to Neptune.

The case is machined from 316L stainless steel and then subjected to low-temperature carbon diffusion, a process that raises surface hardness to roughly 1,200 Vickers — about six times that of untreated steel. The case is finished with bead-blasting, giving it a matte, gray-toned surface that diffuses light, which makes what little wear that does occur far less conspicuous. It measures 44mm wide and 14.3mm high

The dial is composed of nine pieces of oxidized silicon, producing shifting blue-violet interference colours that evoke the depths of space.

Across its surface, hand-painted Super-LumiNova planets trace their real orbital periods — from Mercury’s 87.97 days to Neptune’s 164.80 years — forming a miniature mechanical model of the Solar System.

The strap is made from FKM with a sailcloth texture, and has a purple stitching to complement the dial.
