Strap for Ocean Star Decompression Timer 1961 PVD

The lug width of the Mido Ocean Star M026.807.33.051.00 is 20 millimetres. This measurement is determined by positioning a digital calliper perpendicularly across the case terminals at the base of the lugs. Precise measurement is critical: an undersized strap does not fit into the slots, whilst an oversized strap creates excessive play and drop risk.

The choice depends on intended use and context. For formal occasions, we recommend vegetable-tanned calf or alligator in cognac brown or black tones. For sports and outdoor activities, a NATO strap in technical fabric or rubber provides secure grip and moisture resistance. All straps with 20mm lug width are fully compatible with this model.

Use a spring bar removal tool or small flat screwdriver. Insert the tool into the slots beneath the lug, compress the internal spring of the pin to release it, then extract the old strap. Align the new strap with the slots, reinsert the pins with the internal spring compressed until they click into place. Verify secure attachment before wearing the watch.

Yes. The M026.807.33.051.00 accepts any strap with a 20mm lug width. Bespoke aftermarket straps, crafted from premium leather, technical NATO fabric, or rubber, are entirely compatible and provide an excellent opportunity to personalise the timepiece. Ensure the lug width is precisely 20mm and that the pins are standard diameter.

A high-quality leather strap (calf, alligator, shell cordovan) typically lasts 5–8 years with daily wear, depending on climate, humidity, and maintenance. Leather develops a natural patina over time. In humid or chlorinated environments (sea, pool), wear accelerates to 2–3 years. Technical straps in NATO or rubber offer superior durability (10+ years) with less visible patina development.
