OMEGA Dynamic Bracelet ST 1570 / 870: A Distinctive Stainless Steel Design for an Iconic Watch

The OMEGA Dynamic ST 1570 / 870 bracelet is a purpose-built stainless steel bracelet designed exclusively for the unique case shape of the OMEGA Dynamic III series, introduced in the late 1990s. This bracelet is a perfect match for the Dynamic line’s distinctive, elliptical case design and bold aesthetic, providing not only structural compatibility but also a seamless, integrated look that completes the visual identity of the watch.

With its clean lines, solid construction, and ergonomic wrist feel, the ST 1570 / 870 bracelet reflects OMEGA’s intent to offer a modern, youthful alternative to its more traditional collections—while still maintaining the precision and quality of Swiss watchmaking.

Reference Breakdown

• ST: This prefix signifies stainless steel construction, using high-quality 316L steel. This material is durable, corrosion-resistant, and ideal for daily wear while maintaining a professional appearance.

• 1570: The bracelet design number. It features a flat, solid three-link design, wider than typical De Ville or Seamaster bracelets from the same era, and optimized to match the elliptical, tonneau-style Dynamic case. The links are broad and squared, contributing to the bracelet’s strong wrist presence.

• 870: The end link reference, specifically engineered to fit the OMEGA Dynamic III case. Unlike most traditional spring-bar systems, the Dynamic case uses screw-in bars or special mounting hardware, meaning this bracelet is only compatible with Dynamic cases using the 870 end link interface.

Key Features

• Material: Full stainless steel, brushed on the top surface for a sportier aesthetic, with light polishing on the sides for contrast

• Link Style: Broad, three-piece links that taper subtly toward the clasp, offering both visual strength and wrist comfort

• End Links: Unique 870 end links designed exclusively for the elliptical Dynamic III case—not interchangeable with standard round-lug watches

• Clasp: Folding OMEGA-signed deployant clasp, secure and sleek, built for reliable performance

• Wearing Comfort: Medium-to-heavy weight, with smooth articulation and a flush fit that follows the curve of the wrist and case

This bracelet was created to match the modern, slightly unconventional design philosophy of the Dynamic line—offering an alternative to the more conservative styles of De Ville or Constellation.

Compatibility

The ST 1570 / 870 bracelet is compatible only with:

• OMEGA Dynamic III models, including both automatic and quartz references from the late 1990s

• Dynamic cases using screw-in bar systems and 870-specific end link fitment

• Not compatible with standard lug watches (De Ville, Seamaster, Speedmaster, etc.)

Why It’s Desired

• Factory-Correct Fit: One of the only OEM bracelets made specifically for the third-generation Dynamic

• Unique Aesthetic: Broad, modern links designed to complement the distinctive Dynamic case

• Comfortable and Durable: Built for daily wear with ergonomic design and reliable construction

• Hard to Find: Dynamic parts are now increasingly rare, especially in excellent condition with original finish and tight links

Final Thoughts

The OMEGA Dynamic ST 1570 / 870 bracelet is a standout in OMEGA’s catalog, offering a precise fit and bold design tailored exclusively for the Dynamic III. For collectors, restorers, or fans of this experimental and stylish line, the 1570 / 870 is the authentic finishing touch that completes the look and feel of a true modern classic.
