Strap for Ocean Star 600 Chronometer DLC / Black / Rubber

The lug width of the Mido Ocean Star M026.608.37.051.00 is 22 millimetres. This measurement represents the distance between the two lugs where the strap attaches to the case. To verify this dimension, measure the distance between the lugs: a tolerance of ±0.5 millimetres is acceptable to ensure correct ergonomic fit.

For the M026.608.37.051.00, we recommend a vegetable-tanned leather strap in a dark shade (black or deep brown), 4 millimetres thick with a tapered profile. This choice emphasises the diver's marine identity, develops a natural patina over time, and creates balanced contrast with the bidirectional ceramic bezel. Alternatively, a navy NATO strap or charcoal rubber maintains the sportive character without aesthetic affectation.

Strap removal is accomplished via extraction of the spring bars that anchor the strap to the lugs. Procure a spring bar tool, position it beneath the bar on the lower side, push upward until the spring is released, and withdraw the exhausted strap. Insert the new strap by aligning the holes correctly, reinsert the spring bar until you hear the locking click. Verify that the strap does not experience unwanted torsion before wearing the timepiece.

All straps with a 22-millimetre lug width are mechanically compatible with the M026.608.37.051.00. This includes vegetable-tanned leather, alligator leather, silicone, FKM rubber, NATO fabric, and cordura webbing. Always verify that the strap thickness (typically 3.5 to 5 millimetres) does not create excessive tension on the lugs. Artisanal straps are often customisable in colour, grain finish, and buckle type, permitting infinite aesthetic combinations whilst maintaining total mechanical compatibility.

A high-quality vegetable-tanned leather strap, subjected to moderate use and appropriate care, typically lasts 4–6 years before requiring replacement due to structural aging. Factors influencing longevity: frequency of immersion (saltwater accelerates aging), rapid drying after immersion, absence of torsional stress, periodic conditioning with natural waxes. A rubber or silicone strap lasts 7–10 years under regular sports-marine use conditions. The patina that develops over time is a desirable characteristic, not a defect.
