The 123.10.38.21.51.001 is the Constellation 38mm with the black dial and diamond markers. The Constellation is the dressiest line Omega makes, defined by the four claws on the bezel, and this config adds diamonds to the black dial. It is the evening-wear version of the Constellation.

The dial. Deep black with diamond markers. The black is the backdrop, and the diamonds sit in rhodium-plated holders. Eleven diamond markers, with the date at 3 taking the twelfth position. Rhodium hands. It is the high-contrast dress dial, black and sparkle, and it reads as the most formal dial in the Constellation range.
The case. 38mm, the mid-size Constellation. The defining feature is the four Griffes, the polished claws that grip the bezel and crystal. The bezel is brushed steel with engraved Roman numerals. The claws against the brushed bezel are the Constellation signature, and VSF has the shape right.
The bracelet. The mono-rang integrated bracelet. Horizontal brushed links connected by polished barrel hinges, which gives it the jewelry-like drape. Hidden butterfly clasp keeps the closure clean.
The movement. DD8500, the Co-Axial clone with the jumping hour hand. The independent hour hand lets you change time zones or adjust the date without stopping the seconds hand. Decorated with blackened screws and Geneva waves in arabesque, visible through the exhibition caseback.
The takeaway. The Constellation is Omega's dress watch, and the black diamond dial is its most formal configuration. The claws, the Roman numeral bezel, and the diamond markers all point in the same direction. The DD8500 jumping hour is the functional piece, and the 38mm size wears like a proper dress watch. If you want an Omega that reads as jewelry-adjacent without going full gold, this is the one. The diamonds on black are the cleanest version of that look.
