The lug width is 20 millimetres. This dimension indicates the strap width at the point of attachment to the case lugs.

The strap is changed by removing the spring bars that connect the strap to the case lugs. Use a dedicated spring bar tool to gently lever the pins and create working space.

A quality vegetable-tanned calf strap, with proper maintenance, lasts between 3 and 5 years of daily wear. Alligator, being a more delicate material, typically shows signs of wear after 2–3 years. Replacement frequency depends on exposure to moisture, perspiration, and maintenance practice. Periodic conditioning with dedicated oils significantly extends useful life.
