OMEGA Seamaster Bracelet ST 6155 / 449: Vintage Integration with Quartz-Era Character

The OMEGA Seamaster ST 6155 / 449 bracelet is a classic component from OMEGA’s early 1980s lineup, designed to complement the brand’s transition into the quartz era. While modern Seamaster bracelets tend to lean toward bold and sporty designs, the 6155 / 449 stands out with a streamlined, integrated aesthetic typical of the time. It pairs perfectly with cushion- and tonneau-shaped Seamaster cases, offering a seamless visual connection and a comfortable wrist presence.

Collectors of vintage OMEGA quartz models often seek this bracelet for its correct fit, period styling, and hard-to-find original construction.

Breaking Down the Reference

• ST: Denotes stainless steel (acier inoxydable), OMEGA’s standard material for durability and resistance to corrosion.

• 6155: Refers to the bracelet’s core design. This series features flat, compact horizontal links, designed to flow into the case with minimal gap and maximum wrist comfort.

• 449: Indicates the solid end links that connect the bracelet to specific Seamaster cases—most notably those with semi-integrated or full integration, popular in the early 1980s.

The ST 6155 / 449 was typically mounted on watches with a 36–38mm case size, optimized for ergonomic wear and visual balance.

Key Features

• Material: Fully brushed stainless steel with a matte finish

• Link Design: Flat “brick-style” horizontal links, tightly spaced for fluid movement

• End Links: Solid 449 end links engineered for cushion-shaped cases with integrated lugs

• Clasp: Fold-over clasp with engraved OMEGA logo—secure and reliable

• Style: Understated and professional, reflecting the era’s minimalist design approach

The bracelet maintains a uniform width with minimal taper, giving it a bold, stable wrist presence. Though slim by modern standards, it offers excellent comfort and a vintage-correct look.

Compatibility

The ST 6155 / 449 bracelet was originally used on OMEGA Seamaster Quartz models, such as:

• Reference 196.0102

• Other quartz-driven Seamasters from the early 1980s with cushion or tonneau-shaped cases and semi-integrated lugs

This bracelet is not compatible with modern Seamaster Diver 300M models or any watch with straight lugs or 20mm lug widths.

Why Collectors Seek It

• Authenticity: Period-correct bracelet for early quartz Seamaster models

• Comfort: Flat links and smooth articulation provide excellent daily wearability

• Unique Design: Represents a design era when watches and bracelets formed one visual unit

• Rarity: No longer in production; becoming difficult to source in clean, original condition

Final Thoughts

The OMEGA Seamaster ST 6155 / 449 bracelet is a prime example of vintage OMEGA design at its most refined and integrated. For owners of early-’80s Seamaster quartz watches, it’s more than just a bracelet—it’s a vital part of preserving the character and historical accuracy of these transitional-era timepieces. With its comfortable fit and understated charm, the 6155 / 449 continues to hold value for both collectors and daily wearers.
