Strap for Divers Sixty-Five 43 Chronograph Bronze / Blue / Carl Brashear Limited Edition

The lug width of this model is 21mm. This measurement allows precise identification of compatible straps and ensures balanced proportions between the 43mm case and the strap itself, avoiding unwanted lateral overhang.

The choice depends on intended use: for daily elegance, vegetable-tanned calf leather develops natural patina over time; for frequent diving, natural rubber straps guarantee secure fit and salt-water resistance; for versatility, alligator offers durability and luxury aesthetics; for sportiness, NATO straps in Cordura maintain functionality and quick changes.

Strap replacement involves removing the spring bars connecting the case to the original strap. Using a spring bar tool, compress the bars, extract the old strap, and position the new one by aligning the lugs with the case holes. No specialised equipment is required beyond a standard spring bar tool, readily available online.

All straps with 21mm lug width are compatible. Milanostraps offers a specialised collection in leather, alligator, shell cordovan, rubber and NATO, all certified for 21mm lugs and ready for dispatch. Always verify lug width before purchase.

A high-quality vegetable-tanned calf strap lasts 3-5 years with daily use, reducing to 1-2 years if frequently exposed to salt water. Alligator leather resists longer (5-7 years) due to skin structure. For regular diving use, we recommend rubber or technical textiles. Proper maintenance—swift drying and periodic conditioning—extends longevity considerably.
