Strap for Ocean Star Tribute Gradient Stainless Steel / Grey

The Mido Ocean Star M026.830.17.081.00 features a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 21.00 mm. This dimension is characteristic of the Ocean Star diver collection models and requires significant constructive precision during strap coupling. Straight or slightly angled lugs of 21 mm ensure orthogonal adhesion to the case without dead space or anomalous tensions.

There is no univocal answer, but selective criteria apply. A strap in <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> reflects the model's professional vocation: contained thickness (1.4–1.6 mm), visible ageing, natural patina. For more formal contexts, black-dyed <a href="/pages/termine-glossario/alligatore">alligator</a> with a stainless steel <a href="/pages/termine-glossario/deployante">deployant clasp</a> amplifies aesthetic authority. Technical nylon NATO straps remain the versatile choice for excursions and splash-prone environments.

The Mido Ocean Star M026.830.17.081.00 employs standard straight lugs. For replacement, a dual-end extraction tool (spring bar tool) is required: position the pin in the lateral grooves of the spring, apply gentle upward pressure, and extract the pin from its seat. The new strap must present perfectly aligned holes: a 0.5 mm offset compromises coupling orthogonality. We recommend installation service at Casati Milano to guarantee mounting geometry.

All universal straps with a <a href="/pages/termine-glossario/misura-ansa">21 mm lug width</a> are formally compatible. However, the constructive quality of the spring hole must guarantee tolerances of ±0.1 mm: budget straps often present off-centre holes, generating anomalous friction on the spring. We recommend exclusively full-grain leather artisanal straps, high-density nylon NATO, or vulcanised elastomers.

Durability depends on tanning type, thickness, and environmental exposure. A vegetable-tanned 1.5 mm leather strap with moderate daily use (8–10 hours per day) maintains structural integrity for 3–4 years before showing signs of lug failure. Natural <a href="/pages/termine-glossario/patina">patina</a> begins after 4–6 weeks. If exposed to constant humidity (marine environments, heavy perspiration), the cycle shortens to 18–24 months. Shell cordovan straps, thanks to fibre density, extend service life to 5–6 years under ordinary conditions.
