Omega Constellation reference 123.15.27.20.01.001 features a black dial with scattered silver star motif indices, a diamond-set bezel, and a date aperture at 3 o'clock, housed in a stainless steel case with the signature Constellation claw lugs and integrated brushed steel bracelet. Automatic movement with Si14 silicon hairspring, sapphire exhibition case back, 27mm, circa 2022, unworn at 9.75/10, full set including box, warranty card, and extra link, 6-inch bracelet length.

Omega was founded in La Chaux-de-Fonds, Switzerland in 1848 and has since become one of the most recognized and technically accomplished Swiss watch manufacturers in the world, known for outfitting NASA astronauts, timing the Olympic Games, and producing the Speedmaster — the only watch worn on the moon. The Constellation collection, introduced in 1952, represents Omega's flagship dress watch line and has been worn by cultural icons and heads of state across more than seven decades of continuous production. The reference 123.15.27.20.01.001 with its black star dial is a particularly distinctive variant within the current Constellation lineup, replacing the standard applied indices with a scattered celestial star pattern that transforms the dial into a miniature night sky — a design choice that elevates the piece from elegant dress watch to wearable art. The Si14 silicon hairspring used in this reference is a significant technical detail, providing superior resistance to magnetic fields and temperature variation compared to traditional hairspring materials, and is visible through the exhibition sapphire case back. For the collector, the gift buyer, or the wearer seeking a near-mint, full-set Omega with a truly distinctive dial, this unworn example represents exceptional value and immediate wearability.
