Strap for Ocean Star 600 Chronometer Stainless Steel / Black / Bracelet

The lug width of the M026.608.11.051.00 is 22mm. This measurement is taken between the metal lugs (pins) that connect the case to the strap. Precision is essential when ordering an aftermarket strap, as even a 1-2mm discrepancy will compromise fit and safety.

We recommend three options for this diver: (1) Vegetable-tanned alligator strap for transitioning between sports and semi-formal contexts; (2) Technical NATO strap in robust canvas (navy blue, black, or slate grey) to emphasise the watch's dive heritage; (3) FKM rubber for frequent saltwater use, which resists degradation where leather fails. Selection depends on primary use case and aesthetic preference.

Procedure: (1) Place the watch on a stable surface with the case facing upward; (2) Locate the spring bar (pin) securing the lug to the current strap; (3) Use a spring bar tool to compress the internal spring mechanism and release the old strap; (4) Insert the new strap by threading the spring bar through the new keeper; (5) Verify complete engagement of the spring bar and confirm the strap has no lateral play. Repeat for both lugs.

Yes, the M026.608.11.051.00 accepts any strap with a 22mm lug width, provided it was engineered for case diameters between 40–45mm and standard mounting thickness. Quality aftermarket straps—vegetable-tanned leather, premium NATO, or technical rubber—fit perfectly. Ensure the new strap does not impose excessive stress on the case during installation.

A quality leather strap (alligator or calf with vegetable tanning) typically lasts 3–5 years with regular maintenance if worn 4–5 days per week. Intensive saltwater use or humid environments reduce this to 1–2 years. To extend longevity: rinse the strap after saltwater contact, avoid prolonged direct sunlight, and periodically apply protective wax. Rubber or NATO straps last 5–10 years with identical maintenance protocols.
