Strap for Divers Sixty-Five 40 Stainless Steel / Bronze / Blue / Calf

The lug width of this model is exactly 20mm, measured as the internal distance between the two case lugs. This measurement is critical to ensure proper strap mounting without stress on the watch attachments or lateral play.

The best strap depends on usage: for vintage authenticity with bronze patina, we recommend vegetable-tanned alligator or aged shell cordovan. For colour versatility, traditionally tanned calf in cognac or dark tones. For diving functionality, NATO strap in cotton or water-repellent rubber.

Use a spring bar tool to gently push the spring bar inward, creating space to extract the attachment ring from the lugs. Repeat on the other end. Insert the new strap by positioning the attachment ring in the lugs and verify the spring bar is fully locked in its socket. Extreme care is required to avoid scratching the case.

Yes, any aftermarket strap with 20mm lug width is physically compatible with the Divers 65. However, we recommend higher-quality straps (vegetable-tanned leather, premium rubber) to preserve the piece's aesthetics and functionality, avoiding budget options that may wear prematurely.

Duration varies based on usage, climate, and maintenance: vegetable-tanned leather straps (alligator, shell cordovan, calf) last 3–5 years in moderate daily use if kept dry. Frequent diving accelerates wear; we recommend drying the strap after prolonged water contact. NATO and rubber straps have superior durability (5–10 years) in humid environments.
