CONSTELLATION ST 1551 - 861

OMEGA Constellation Bracelet ST 1551 / 861: Timeless Stainless Steel Precision for the 19mm Manhattan Series

The OMEGA Constellation ST 1551 / 861 bracelet is a sleek and robust stainless steel bracelet developed for mid-size Constellation Manhattan models with 19mm integrated lugs, produced during the 1990s and early 2000s. It features OMEGA’s celebrated mono-rang (single horizontal link row) design—crafted for elegant integration, comfortable daily wear, and long-term durability.

As a factory-original bracelet, the ST 1551 / 861 is ideal for collectors, restorers, and enthusiasts looking to complete a watch with the correct OEM fit and finish. It delivers a seamless continuation of the case into the bracelet, upholding the legacy of the Constellation line’s integrated architecture.


Reference Breakdown

  • ST: The prefix “ST” confirms the bracelet is made entirely of stainless steel. This construction ensures excellent resistance to wear and corrosion, along with a timeless aesthetic suitable for any setting.

  • 1551: This design number represents a continuation of OMEGA’s mono-rang bracelet concept—featuring a single row of wide, flat horizontal links. Compared to earlier references like the 1448 or 1550, the 1551 series offers a more modernized feel while maintaining the graceful, wrist-hugging contour that defines the Constellation Manhattan series.

  • 861: The end link reference, specifically engineered for 19mm integrated-lug Constellation cases. These solid steel end pieces are non-removable and designed to sit perfectly flush with the case, completing the clean and cohesive profile without any visual gaps or break in flow.
