Strap for Divers Sixty-Five 40 Social Club Edition / Kyiv

The lug width is 20mm, a classical dimension characteristic of this model. To verify compatibility with any aftermarket strap, measure the distance between the lugs: it must be exactly 20mm. This historical standard grants access to a comprehensive collection of artisanal straps.

The ideal strap depends on use: for regular diving, natural vulcanised rubber (black or navy). For daily urban wear, alligator vegetable-tanned cognac or brown scotch grain calf. NATO canvas straps in khaki amplify military heritage. All must be 20mm for compatibility with the lugs.

The procedure is straightforward: using a flat tool (strap change tool or precision screwdriver), gently press the spring bar inward from below. The spring retracts and the lug releases. Repeat on the other side. Insert the new strap, aligning one end first, then push until the spring bar clicks into place. No specialised equipment required.

Yes, provided they are 20mm. An artisanal-quality strap from a maker such as Casati Milano offers advantages over the original: colour personalisation, choice of noble materials (alligator, shell cordovan, vegetable-tanned leather), and superior finish. Compatibility is guaranteed by lug width, not brand affiliation.

Durability depends on materials and use. Vegetable-tanned alligator lasts 3–5 years with regular maintenance (cleaning, conditioning). Structured calf follows a similar cycle. Canvas NATO straps endure 5–7 years. Vulcanised rubber fatigues after 2–3 years of frequent diving, though it is easily replaceable. Leather patina and ageing are desirable; rubber deteriorates without aesthetic appeal.
