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

The lug width of this model is 20 millimetres. This measurement refers to the internal distance between the two lugs of the case and is the fundamental parameter for selecting a compatible strap. Always verify that the strap you purchase is exactly 20mm to guarantee a perfect fit.

For this dive watch, full-grain leather straps with vegetable tanning, which develop natural patina over time, are ideal. If you intend intensive water use, opt for vulcanised rubber or NATO fabric straps. Natural alligator is elegant for formal contexts, whilst shell cordovan offers the best compromise between aesthetic durability and marine functionality.

Strap replacement requires a specific tool (spring bar tool). Insert the small hook into the slot at the base of the lug, push gently inward to compress the internal spring of the locking bar, and extract carefully. Repeat on the other side. Insert the new strap into the seat, ensuring the locking spring clicks into position. If inexperienced, consult a certified workshop.

Yes, provided the aftermarket strap is exactly 20 millimetres in lug width and that the terminations (straight or slightly shaped) respect the case lugs. Straps of artisanal quality from specialised manufacturers often offer superior construction and comfort to originals whilst maintaining full compatibility.

A full-grain leather strap with vegetable tanning, on a watch with occasional water use, has an average lifespan of 3–5 years before showing visible signs of wear. Frequent exposure to sea water reduces this estimate to 2–3 years. Excellent maintenance (immediate drying, occasional neutral wax treatment) significantly extends strap life.
