OMEGA Constellation Bracelet BA 1448 / 431: Iconic Integrated Design in Solid 18K Yellow Gold

The OMEGA Constellation BA 1448 / 431 bracelet is a stunning example of OMEGA’s luxury craftsmanship, built entirely from solid 18K yellow gold. It was developed for the OMEGA Constellation Manhattan series, particularly models produced during the late 1980s through the 1990s. This bracelet is designed to integrate directly into the case without spring bars, forming a seamless, monobloc look that has become a hallmark of the Constellation line.

The BA 1448 / 431 is not just a bracelet—it is an integral part of the watch’s architecture. For collectors or enthusiasts who own a solid gold Constellation case, this bracelet represents the ultimate pairing of iconic design and precious metal prestige.

Reference Breakdown

• BA: This prefix indicates solid 18-carat yellow gold (boîtier or jaune), meaning every link, end piece, and clasp is made from real, high-value gold—not plated or capped.

• 1448: The bracelet design code. The 1448 series features the signature “mono-rang” design—flat horizontal links with fine brushing, often with polished center accents, creating a sleek, architectural aesthetic. It was developed for OMEGA’s integrated case/bracelet design, introduced in the original Constellation Manhattan collection.

• 431: The end link reference, tailored specifically for mid-size Constellation cases with integrated lugs. These end links are not separate pieces but flow directly into the case, creating a uniform appearance and providing structural strength to the entire watch.

Key Features

• Material: Full 18K yellow gold, finished with brushed surfaces and polished highlights to reflect luxury and precision

• Link Structure: Horizontal bar-style links in a single row ("mono-rang") configuration for smooth flexibility and a clean aesthetic

• End Integration: Custom-shaped 431 ends that fit directly into the Constellation case—this bracelet cannot be interchanged with standard lug systems

• Clasp: Slim folding clasp in solid gold, engraved with the classic OMEGA symbol, ensuring a secure and elegant closure

• Wearing Experience: Lightweight for solid gold, perfectly contoured to hug the wrist, offering exceptional comfort and elegance

This bracelet enhances the overall harmony of the Constellation design, known for its Roman numeral bezel, claw-like “Griffes,” and iconic integrated architecture.

Final Thoughts
