OMEGA Seamaster Bracelet ST 6501 / 827: A Rare and Robust Fit for Full-Size Professionals

The OMEGA Seamaster ST 6501 / 827 bracelet is a lesser-known but highly capable stainless steel bracelet designed for the full-size Seamaster Professional 300M lineup. Built during the late 1990s and early 2000s, this bracelet reflects OMEGA’s commitment to durability, ergonomic comfort, and precise integration, tailored for demanding use—whether underwater or on land.

This bracelet belongs to the same generation that introduced robust upgrades over earlier 1500-series bracelets, including solid link construction, refined machining, and improved end-link fitment. It remains a desirable option for collectors and wearers who prioritize both functionality and original design integrity.

Reference Breakdown

• ST: The prefix indicates stainless steel (acier inoxydable), OMEGA’s standard for corrosion-resistant, marine-grade metal.

• 6501: This design number identifies a bracelet series with a three-link layout, known for its balance of ruggedness and comfort. Often seen as a sibling to the more widely known 6502, the 6501 stands out for subtle differences in finish, taper, or production variation.

• 827: These are solid end links, precisely machined to integrate with Seamaster 300M cases featuring 20mm lug widths, ensuring a flush fit with the watch case.

Key Features

• Material: Full brushed stainless steel for a matte, non-reflective appearance—ideal for dive watch aesthetics

• Link Design: Three-piece solid link structure with a broad center link for added visual presence and wrist comfort

• End Links: Solid 827 end links, offering perfect case integration with no play or gaps

• Clasp: OMEGA-signed fold-over clasp with push-button release and diver extension, designed for wetsuit use

• Profile: Slight taper toward the clasp, maintaining a bold but wearable wrist feel

The bracelet’s simplicity is its strength—it delivers a clean, tool-watch look that is right at home on the wrist of an active diver or everyday wearer.

Compatibility

The ST 6501 / 827 bracelet is compatible with full-size Seamaster Professional Diver 300M models, including:

• 2531.80 – Blue wave dial automatic

• 2541.80 – Quartz variant

• 2254.50 – Sword hands, black dial

• Other Seamaster 300M models from the same case family with 20mm lugs

It is not compatible with mid-size models (36mm), which require narrower bracelets and different end-link types such as 824 or 826.

Why Enthusiasts Appreciate It

• OEM Quality: A factory-original part that maintains the authenticity of vintage and early-2000s Seamaster models

• Strong and Reliable: Built with solid links and diver-ready features

• Distinct Yet Familiar: Offers the performance of the 6502 with unique reference designation

• Collectible Rarity: Less commonly seen on the market, making it a desirable find for OMEGA fans
