OMEGA Seamaster Bracelet TB 1504 / 826: Premium Engineering for Mid-Size Dive Classics

The OMEGA Seamaster TB 1504 / 826 bracelet is a stainless steel bracelet crafted for the mid-size Seamaster Professional Diver 300M watches, specifically those with a 36.25mm case diameter and 18mm lug width. This bracelet, part of OMEGA’s renowned 1504 series, offers a solid, modernized five-link design, perfectly suited to the proportions of mid-size dive watches from the late 1990s and early 2000s.

The TB 1504 / 826 is often considered the premium mid-size companion to the full-size 1504 / 825—sharing the same visual language and structure, but scaled for a more compact and comfortable fit. It represents a transition to heavier, more solidly constructed bracelets, especially when compared to earlier 1501 and 1502 versions.

Reference Breakdown

• TB: A factory or regional code prefix that does not affect the physical design—it may indicate a specific batch or distribution channel. Functionally and structurally, it remains identical to standard ST or DB variants.

• 1504: The bracelet design series. Known for its five-piece solid link structure, the 1504 line improved upon earlier models by offering enhanced durability and smoother articulation.

• 826: The solid end link reference, precisely machined to integrate with 36mm Seamaster Professional cases. These end links ensure a flush, stable fit between the bracelet and the case.

Key Features

• Material: Solid stainless steel, fully brushed with subtle polishing on the interior links for a classic OMEGA two-tone texture

• Link Structure: Five-piece solid links for durability and flexibility; no folded or hollow parts

• End Links: Solid 826 end links engineered to fit 18mm lugs on mid-size cases with zero gaps

• Clasp: Fold-over clasp with OMEGA engraving, double push-button release, and diver extension

• Profile: Gently tapering toward the clasp, designed to balance the mid-size watch head comfortably on the wrist

This bracelet is both practical and elegant—light enough for everyday wear, yet tough enough for actual diving.

Compatibility

The TB 1504 / 826 bracelet is factory-fitted to mid-size Seamaster Professional Diver 300M references, including:

• 2561.80 – Quartz model with blue wave dial

• 2252.50 – Automatic version with black dial

• 2262.50 – Quartz, sword hands, black dial

All models must have 18mm lugs and a case diameter of approximately 36.25mm.

It is not compatible with full-size Seamaster Professional 41mm models, which use wider end links like 825 or 830.

Why It’s Desirable

• Original Equipment: Correct bracelet for many late-1990s to early-2000s mid-size Seamasters

• Improved Construction: Fully solid links make it stronger and more refined than earlier designs

• Comfort: Excellent articulation and lightness for all-day wear

• Visual Harmony: Seamlessly matches the wave dial and helium valve aesthetic of the Seamaster 300M line

Final Thoughts

The OMEGA Seamaster TB 1504 / 826 bracelet represents the best in mid-size dive watch design—offering strength, precision fit, and a timeless appearance. For collectors, restorers, or everyday wearers, it’s the definitive bracelet to complete any mid-size Seamaster Diver 300M.
