Reference Breakdown

• BA: The “BA” prefix denotes that this bracelet is made from solid 18K yellow gold. Unlike plated or capped alternatives, this bracelet is forged entirely in gold, offering genuine luxury, durability, and investment-grade value.

• 6551: The bracelet design number. It follows the iconic “mono-rang” (single-row) horizontal bar link format used across Constellation models. The 6551 version, however, features broader, slightly flatter links compared to earlier generations, delivering a more contemporary and assertive appearance while preserving the elegant silhouette.

• 863: The end link reference, designed to integrate precisely with OMEGA Constellation Manhattan cases with 19mm lug width. These solid gold end links are not removable like traditional spring-bar ends; they are engineered to fit flush with the case as part of OMEGA’s integrated bracelet system.
