Strap for Ocean Star Decompression Timer 1961

The lug width of the Mido Ocean Star M026.807.11.051.00 is 20 mm. This dimension is measured from lug to lug in the seat where the strap rests. A correctly dimensioned 20 mm strap ensures a secure fit without excessive tolerances, suitable for both robust leather and technical rubber compounds. The measurement must exclude any protective covering material to achieve the required accuracy.

The ideal strap depends on intended use. For formal environments, pressed alligator or English vegetable-tanned calf leather enhances the watch's character whilst developing patina over time. For water activities, a NATO strap in 420D nylon or FKM rubber with fine grain offers complete waterproofing and rapid drying. Shell cordovan represents the versatile compromise: its intrinsic density protects from moisture whilst keeping the watch suitable for both formal contexts and outdoor excursions. All materials available on milanostraps.it are tested for compatibility with the 20 mm lug width.

Strap replacement is straightforward: use a universal strap tool, positioning it on the seat of one of the transverse pins. Apply steady pressure until the lug disengages from the secondary seat (the less critical side). The lug should not be completely removed; the old strap rotates and slides sideways. Insert the new strap (prepared at 20 mm width) following the reverse path until you hear the audible click of the pin seating. The entire operation takes less than one minute and requires no watchmaking expertise.

Yes, the reference M026.807.11.051.00 is fully compatible with artisanal aftermarket straps manufactured at 20 mm lug width. Compatibility depends solely on the passant dimension and installation accuracy. The artisanal straps from milanostraps.it are crafted to precise specifications, ensuring a secure fit without lateral movement. Available materials—leather, NATO, rubber—are tested for resistance and durability on professional instruments comparable to the Ocean Star.

A quality leather strap has an average lifespan of three to four years with moderate daily wear, extendable to five to six years with regular maintenance. Cleaning every three months with a soft brush and hydrophobic treatment every six months preserves elasticity and colour. The natural patina that develops is not deterioration, but aesthetic evolution: micro-abrasions create a sought-after vintage appearance. At the end of its useful life, replacement is immediate and economical. Rubber or NATO straps have longer lifespans (seven to ten years) and require minimal maintenance.
