Strap for Divers Sixty-Five 40 Stainless Steel / Deauville Blue / NATO

The lug width is precisely 20.00mm, measured between the inner pins of the upper and lower lugs. This specification requires dedicated strap solutions compatible with this exact dimension.

Material choice depends on use case: for refined elegance, select alligator or shell cordovan with vegetable tanning in dark brown. For versatile sportiness, cotton-dense NATO. For technical diving, fluoroelastomer rubber in slate-grey or black. All materials are available in 20mm at milanostraps.it.

Use a spring bar tool (specialised lever implement) to extract the elastic pins from the lugs. Insert the tapered tip of the tool into the pin access hole, lift with gentle rotational motion and the pin disengages. Repeat on the opposite side, remove the old strap. Install the new one by aligning the first pin, then apply light pressure until you hear the click of the second pin engaging.

Yes, provided it is compatible with 20mm lug width. Our bespoke straps at milanostraps.it are constructed with lugs precisely configured for this dimension. We advise against budget universal straps: fitment will be inaccurate and compromise the watch's aesthetic integrity.

A quality leather strap, featuring vegetable tanning or shell cordovan, endures 3–5 years of moderate daily wear. Frequent water exposure (diving, showering) reduces longevity to 18–24 months. For regular diving use, rubber or NATO is recommended. The patina that develops is desirable and part of the leather's aesthetic evolution, not degradation.
