OMEGA Constellation Bracelet ST 1550 / 860: Stainless Steel Strength and Style for the 1990s Manhattan

The OMEGA Constellation ST 1550 / 860 bracelet is a robust, full stainless steel bracelet designed for OMEGA Constellation Manhattan models with 19mm integrated lugs, produced in the 1990s. Known for its clean, flat link construction and perfectly integrated design, this bracelet preserves the legacy of the Constellation’s mono-rang style while enhancing the comfort, strength, and visual cohesion of the watch.

This bracelet is a factory-original component made for mid-size references—making it a vital piece for collectors seeking period-correct restoration or for anyone who prefers a minimalist, all-steel look with seamless integration.

Reference Breakdown

• ST: The prefix “ST” designates the bracelet as constructed entirely from stainless steel. This material provides long-lasting durability, corrosion resistance, and a contemporary matte finish ideal for daily wear.

• 1550: Bracelet design code. The 1550 model retains the iconic mono-rang (single horizontal row) layout first introduced in earlier Constellation bracelets, but with a slightly wider and flatter link profile. Compared to the 1448 series, the 1550 looks more substantial and wears a touch more modern while still delivering the slim elegance of the original Manhattan concept.

• 860: The end link reference, precision-engineered to fit 19mm integrated-lug Constellation cases. These end links are specifically shaped to match the curvature and dimensions of the Constellation case, offering a flush, seamless transition with no spring bars or visible lug structures.

Key Features

• Material: Full brushed stainless steel, with polished accents along the link edges and clasp for added depth

• Design: Flat, wide horizontal links in the classic mono-rang configuration, slightly curved to follow the wrist's contour

• End Links: Solid 860 end pieces, matched to 19mm integrated Manhattan cases, ensuring a cohesive and factory-accurate appearance

• Clasp: Hidden fold-over clasp, engraved with the OMEGA logo, built for strength and visual continuity

• Wearing Feel: Comfortable and balanced, with smooth articulation between links and a medium weight that offers substance without heaviness

This bracelet matches perfectly with full stainless steel Constellation models that feature steel bezels, tone-on-tone dials, and the famous "griffes" (claws) flanking the bezel at 3 and 9 o'clock.
