Strap for Oris Divers 65 01 733 7707 4053

The lug width of the Oris Divers 65 01 733 7707 4053 is precisely 20 millimetres. This dimension is faithful to the original 1965 model and reflects Oris's philosophy of maintaining slender, elegant proportions. Measure with a calliper the distance between the inner edges of the two lugs to verify compatibility with a new strap.

The choice depends on intended use and personal aesthetic. For genuine diving, we recommend a butadiene rubber strap with 20mm lugs, resistant to moisture and stress. For elegant everyday wear, an alligator strap with vegetable tanning in brown tones creates chromatic harmony with the dial. For sporting versatility, a NATO textile strap in dark grey or military green maintains vintage authenticity.

Use a spring bar tool to remove the elastic springs securing the strap to the lug bars. Insert the flat tip of the tool into the small lateral hole of the lug, push downward to release the spring, and the strap comes free. Repeat identically on the other side. To install the new strap, align the strap holes with the lugs and press until the spring clicks into place.

All straps with 20mm lug width are compatible with this model. Milano Straps offers a curated selection of leather straps (alligator, calf, shell cordovan), NATO textile, and rubber, each material chosen to enhance the historical and functional identity of the Divers Sixty-Five. Always verify that the strap declares 20mm lug width before purchase.

A quality leather strap with vegetable tanning, worn on a dive watch used occasionally in water, typically lasts 3–5 years before replacement is necessary. Saltwater exposure accelerates ageing: if you use the Oris in the sea, alternate with a rubber strap. The patina that develops on leather over time is natural and desirable, but fibre breakdown is irreversible.
