OMEGA Constellation Bracelet BA 1551 / 861: Solid 18K Yellow Gold Craftsmanship for the Legendary Manhattan Line

The OMEGA Constellation BA 1551 / 861 bracelet is a stunning, fully integrated solid 18K yellow gold bracelet, specifically designed for the OMEGA Constellation Manhattan models produced in the 1990s and early 2000s. Reflecting OMEGA’s highest standards of design and materials, this bracelet is a seamless continuation of the case—turning the watch into a unified piece of functional jewelry.

Crafted with attention to detail, precision fit, and a high-luxury finish, the BA 1551 / 861 is the quintessential choice for those restoring or elevating their Constellation to its original, factory-gold specification.

Reference Breakdown

• BA: This prefix denotes solid 18K yellow gold throughout the bracelet, including the clasp, links, and end pieces. This is not gold-plated or capped—each component is crafted from real gold, adding both aesthetic and intrinsic value.

• 1551: The bracelet design code. It features the unmistakable “mono-rang” horizontal link structure, a single-row link design exclusive to the Constellation Manhattan line. These links are flat, wide, and slightly curved to ensure they hug the wrist while delivering a refined, architectural look.

• 861: The end link reference, engineered to integrate directly with OMEGA Constellation cases with 19mm lug width. These are not traditional end links but rather case-matched components designed to continue the bracelet into the body of the watch without visible lugs or spring bars.

Key Features

• Material: Solid 18K yellow gold, brushed and polished for a dual-finish look—subtle yet striking under light

• Design: Flat horizontal links in the classic “mono-rang” Constellation style, offering smooth articulation and a seamless case-to-bracelet transition

• End Links: Integrated 861 ends, designed specifically for the Constellation Manhattan integrated case architecture

• Clasp: Concealed butterfly-style folding clasp in gold, signed with the OMEGA logo, providing a clean and secure closure

• Wearing Feel: Comfortable and luxurious—light enough to wear daily, but with the unmistakable feel of solid gold on the wrist

This bracelet complements Constellation dials with gold hour markers, Roman numeral bezels, and iconic "griffes" (claws), forming the signature silhouette of the Manhattan line.
