Strap for Divers Sixty-Five 36 Stainless Steel / Blue / Rubber

The Divers 65 features a lug width of precisely 17 millimetres. This dimension represents the internal distance between the two lugs of the case and determines compatibility with aftermarket straps. To verify, insert a caliper into the lug seat and measure the available space: it must correspond to 17mm to guarantee correct ergonomic fit without lateral play.

Selection depends on intended use and aesthetic preference. For formal-sporting wear, alligator or vegetable-tanned calf elevates case sophistication. For robust daily use, a military-spec Cordura NATO strap is practical and versatile. For genuine diving, an FKM (Fluoroelastomer) rubber strap offers superior chemical resistance and reliable performance in wet environments. For understated elegance, shell cordovan develops a captivating patina over time.

Position the watch on a soft pad with the case face down. Use a dedicated spring bar tool to gently compress the elastic pin of the lug. Insert the tool tip into the small lateral groove of the spring bar, apply light pressure to release tension, then remove the strap. Repeat for the other lug. For new strap installation, align the spring bars with the lug seats and push until you hear a click.

Yes, any strap with a 17-millimetre lug width is mechanically compatible. It is advisable to select specialised manufacturers that guarantee precision in width and build quality, to avoid play or premature wear of the original lugs. A high-quality bespoke strap, crafted with vegetable tanning or certified technical materials, extends the watch's service life and enhances user experience.

A high-quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts between 3 and 7 years under normal conditions (occasional daily wear), influenced by ambient humidity, sun exposure and maintenance protocol. A leather strap subjected to repeated submersion or saline environments degrades more rapidly: in such cases, FKM rubber is preferable, as it maintains mechanical properties even after prolonged aqueous exposure. Periodic articulation lubrication and timely drying after extended wetting significantly extend service life.
