Museum Collection 5776.71.56— lug 24mm

The lug width of the 5776.71.56 is 24 millimetres. This dimension is specific to the model and must be measured perpendicularly between the strap attachment pins (from shoulder to shoulder of the pin, excluding the fixing heads). A non-24mm strap would result in excessive play or mounting impossibility.

African alligator with defined grain texture represents the most coherent pairing with the construction rigour of the 5776.71.56. Fine-grained calf leather in neutral colourways (black, brown, grey) is also an excellent choice. Vegetable tanning allows the strap to develop a patina parallel to that of the steel case.

The pins on the 5776.71.56 are accessible via a dedicated tool (spring bar tool). Position the watch with the strap facing upwards, insert the fork of the tool under the pin head, press gently until the pin pops out, then remove the old strap. Insert the new 24mm strap aligning the holes, then snap the pin into position. Verify that the pin is fully inserted before wearing the watch.

No. The lug width is precisely 24mm and does not allow for variations. A 22mm strap would create dangerous play affecting case stability; a 26mm would be impossible to mount. Only 24mm straps guarantee correct fit and preserve the structural integrity of the movement.

A quality leather strap (alligator, calf, cordovan in vegetable tanning) has an average lifespan of 3–5 years with moderate daily wear. Longevity depends on the environment (humidity, perspiration, UV exposure), frequency of wear and maintenance. Artisanal straps with vegetable tanning develop a protective patina over time, extending durability. Atelier Casati Milano offers an 18-month warranty on bespoke straps.
