The Patek Philippe Celestial Grand Complications reference 6104R-001 is a highly sophisticated 44mm timepiece crafted from 18k rose gold. It features a signature rounded case with a thickness of approximately 11.33mm and is distinguished by a fixed bezel set with 38 baguette-cut diamonds totaling nearly 4.3 carats. The watch is powered by the self-winding caliber 240 LU CL C movement, which is visible through a sapphire crystal case back and offers a power reserve of up to 48 hours. It is traditionally paired with a shiny black alligator leather strap featuring a rose gold fold-over clasp decorated with an additional 22 baguette diamonds.
The centerpiece of this model is its black celestial dial, which utilizes three metalized sapphire crystal disks to display the nocturnal sky of the Northern Hemisphere. This intricate system tracks the phases and orbit of the Moon, the apparent movement of the stars, and the meridian passage of Sirius. A silver-toned ellipse frames the portion of the sky visible from Geneva, while skeletonized leaf-style hands indicate mean solar time. Additionally, the watch includes a pointer date complication with a scale running along the outer rim of the dial.
General reviews emphasize the 6104R-001 as a pinnacle of horological artistry, blending high-jewelry aesthetics with complex astronomical functions. Collectors frequently praise the depth and visual brilliance of the multi-layered dial, often describing it as a poetic representation of science. While its 44mm size is considered large for a dress watch, it is noted for its presence and the exceptional level of finishing characteristic of the Patek Philippe Seal. However, due to its extreme rarity and complexity, it is typically available as a “price on request” item or commands significant premiums on the secondary market.
