In 2024, Revolution collaborated with the maison to create the Christiaan van der Klaauw × Revolution Planetarium Prometheus, limited to just six pieces. The watch introduced a first for CVDK — fully lumed planetary displays with hand-applied SuperLumiNova planets, a concept that continues into the watch we present today. Following the success of the Prometheus, the idea emerged to continue exploring the maison’s most ambitious astronomical platform, which is the Grand Planetarium.

The result is The Christiaan van der Klaauw × Revolution Grand Planetarium Eccentric Si14 (Silicium) — a second collaboration that introduces several new elements. To evoke the vastness of the cosmos, the dial is crafted from nine separate pieces of oxidized silicon, producing an iridescent surface that shifts between deep blue and violet depending on the angle of light. While silicon is commonly used in watchmaking for escapements and hairsprings, here it takes on a purely aesthetic role. Through controlled oxidation, a thin oxide layer forms on the surface, creating interference colors that give the dial its distinctive cosmic tone — a deliberate balance of modern materials and traditional watchmaking.

Against this shimmering backdrop, the planets are hand-painted in Super-LumiNova by the maison’s master watchmaker. Each planet’s orbital period is engraved and lumed along its path: Mercury completes its orbit in 87.97 days, Venus in 224.70 days, Earth in 365.24 days, and Mars in 686.98 days, while the outer planets follow their much longer cycles — Jupiter (11.86 years), Saturn (29.46 years), Uranus (84.02 years), and Neptune (164.80 years). Even Earth’s Moon appears beside our planet, adding another poetic layer to the display.

The planetary paths themselves are also partially luminescent, creating a breathtaking miniature cosmic light show when darkness falls. Surrounding the display is an outer zodiac scale, read via a blue triangular indicator positioned opposite Earth. As Earth completes its annual orbit, its position against the zodiac scale reveals where it lies relative to the constellations along the ecliptic — effectively indicating the portion of the zodiac in which the Sun appears from Earth at any given time, while also offering a rough indication of the current month.

The watch is housed in a case made from hardened steel, produced by subjecting 316L stainless steel to low-temperature carbon diffusion, raising the surface hardness to around 1,200 Vickers — roughly six times harder than untreated steel. Finished with bead-blasting, the matte grey surface diffuses light and minimizes visible wear, giving the watch a modern, technical character that complements the celestial display within.

Powered by CVDK’s in-house self-winding manufacture calibre, the movement features the Grand Planetarium module mounted on top and delivers a 60-hour power reserve. It operates at 3 Hz and is equipped with a free-sprung balance for improved stability and precision.

Visually, the movement is striking. It is dominated by a gold rotor shaped in the brand’s logo, while beneath it the bridges are decorated with a laser-engraved star field. Each wheel of the gear train, along with the balance wheel, is supported by bridges tipped with star-shaped motifs, forming the impression of a shooting star with a jewel at its center. The stars themselves are finished with circular graining, while the baseplate features perlage decoration, completing the celestial theme.
