The gold bezel is adorned with black Roman numerals and features the four characteristic "griffes" claws on its sides.

The white dial features applied gold-colored indices, dauphine hands, and a date display at the three o'clock position. Below the twelve o'clock position is the Omega logo, and above the six o'clock position are the Constellation name, the Chronometer Automatic designation, and a gold star. The dial is protected by a sapphire crystal with an anti-reflective coating on the inside.

The crown is signed with the Omega logo. The solid steel case back is decorated with the Constellation observatory medallion.

The original integrated Omega Half Bar bracelet is crafted from stainless steel and 18K yellow gold. Wide steel links connect narrow, two-tone elements with gold halves paired with steel sections.

Unlike the Full Bar version, the gold does not span the entire width of the links. The bracelet flows seamlessly into the case, and its gold details harmonize with the gold bezel. The ensemble is completed by the original Omega clasp.

Constellation is among Omega’s most recognizable collections, associated with precision, elegance, and distinctive design. This piece from 2000 represents the "Half Bar" variation, combining stainless steel with 18K yellow gold.

The observatory medallion on the caseback pays tribute to the brand's historic achievements in chronometric precision.
