Strap for Divers Sixty-Five 36 Stainless Steel / Bronze / Black / Rubber

The lug width of this model is precisely 17 millimetres. This measurement represents the internal width of the space between the watch lugs (the attachment points for the spring bars). Verifying this specification is absolutely essential to ensure complete compatibility with aftermarket straps, as even minor variations can result in poor fit and compromised security. Measure directly from the inside of the left lug to the inside of the right lug to confirm the 17mm dimension.

The choice depends on your intended usage and aesthetic preference. For formal elegance, we recommend alligator or vegetable-tanned calf leather in dark brown, cognac, or black tones. For regular diving activity, a vulcanised rubber strap offers excellent water resistance and easy maintenance. For versatile sportswear, a NATO strap in acrylic fabric (navy blue or olive green) echoes the military heritage of the original diver watches. Given the proportionate 36mm case, optimal strap thickness should not exceed 4mm when finished, maintaining the watch's elegant profile.

The Divers 65 features standard spring bar attachments. To replace the strap, use a dedicated spring bar removal tool to compress the spring bars and facilitate extraction from the lug seats. Work with care to avoid damaging the case finish. Align the new strap's lugs with the lug holes before slowly releasing the spring bars into their stable position. If you lack experience, contact a professional: the craftsmen at Casati Milano atelier can execute this operation with precision and care.

Absolutely. Numerous quality manufacturers produce straps specifically sized for 17-millimetre lugs. Milano Straps offers a dedicated collection for this specification: you will find options in premium leather (alligator, calf, shell cordovan), NATO fabric, and rubber. Always verify that your chosen strap is certified for 17mm lug width to guarantee geometric compatibility and long-term stability.

Strap longevity depends on leather quality, construction excellence, and usage patterns. A strap crafted from premium leather (alligator or vegetable-tanned calf) by professional artisans typically lasts 3–5 years with moderate daily wear. Vegetable-tanned leather improves aesthetically over time, developing natural patina, though it requires periodic maintenance. Rubber and NATO straps generally offer longer durability (5–8 years) but less aesthetic evolution. Humidity, perspiration, and sun exposure accelerate wear; proper storage and regular cleaning significantly extend strap lifespan.
