Strap for Divers Sixty-Five 40 Stainless Steel / Bronze / Green / Bracelet

The lug width is 20 mm. This specification determines the strap width compatibility and is measured between the inner spring bar slots of the case lugs. The full collection of 20 mm compatible straps is available on milanostraps.it in various materials.

The choice depends on intended use and aesthetic preference. For Heritage formality, we recommend shell cordovan in vegetable tanning, dark brown. For sport versatility, a polyamide NATO in navy or black. For water immersion, an FKM rubber in blue or black. For formal-smart integration, black alligator on a silver deployante clasp offers uncompromised elegance.

Use a spring bar tool. Secure the watch in a leather pillow, insert the tool under the lug to compress the internal spring of the pin, and carefully remove the spring bar from the lug. Repeat on the opposite side. Install the new strap by reversing the process: insert the spring bar into the compressed spring until it locks securely.

Yes. All straps in the 20 mm collection of milanostraps.it are engineered for this lug width specification. Always verify the 20 mm specification during purchase. The platform offers live consultation and bespoke customisations through Atelier Casati Milano by appointment.

Durability depends on material quality and usage patterns. High-grade shell cordovan in vegetable tanning resists degradation for 5–8 years with regular care. Standard calf leather lasts 3–5 years. Water exposure significantly shortens leather lifespan. We recommend FKM rubber straps for frequent aquatic use, reserving leather straps for daily dry wear or occasional formal occasions.
