Museum Collection 5756.30.01— lug 20mm

The lug width is 20 mm. This standard is specific to the 5756.30.01 model and represents the distance between the lugs that protrude from the case. Any external strap must have this width to fit correctly without movement or forcing.

Dark brown alligator or shell cordovan are the most coherent choices with the classic-elegant identity of this timepiece. Alligator enhances the patina of rose gold over time, while shell cordovan offers superior water resistance and a fascinating color depth. Vegetable-tanned calf is also excellent if you prefer sustainability and natural texture.

The strap is changed using a spring bar tool (a special tool with a fork) to compress the two metal pins (spring bar) that hold the strap to the case. Insert the tip of the fork into the lateral spaces of the pin, gently press downward and remove the old strap. Insert the new strap in the same manner, ensuring the pins snap correctly into the case holes.

Yes, absolutely. This is one of the advantages of this collection: the 20 mm lug width is a standard size well-represented in the artisanal strap market. On milanostraps.it you will find a wide selection of 20mm customizable straps, from premium materials (alligator, shell cordovan) to custom finishes.

A quality alligator or shell cordovan strap lasts 4-7 years with daily use, developing a fascinating patina during this period. Vegetable-tanned calf tends to show more visible wear after 3-5 years due to natural porosity, but maintains structural integrity. Longevity depends on humidity cycles, perspiration and sun exposure. Casati Milano offers an 18-month warranty on custom straps.
