Strap for Big Crown Diamonds 38 Stainless Steel / MOP

The lug width is 19 millimetres. This measurement represents the internal space between the lugs where the strap is inserted. It is essential to verify this dimension before ordering an aftermarket strap, measuring it with a ruler on the inside of the lug itself.

The choice depends on usage: a calf leather strap with vegetable tanning offers daily elegance; alligator guarantees a noble patina over time; a NATO references the watch's avionic origins; rubber is ideal for technical and sporting contexts. All materials must have a 19mm lug width to ensure compatibility.

The change is made using a dedicated tool (spring bar tool) to extract the pins from their sockets. Insert the flat end of the tool into the spaces between the lug and strap, gently push the pin towards the centre of the watch and the strap will be released. Repeat on the opposite side. To fit the new strap, position the pins in the holes and press until you hear a click.

Yes, any strap with a 19 millimetre lug width is compatible. Our handcrafted straps on milanostraps.it are available in this size with various material and finish options. We recommend always verifying the measurement before purchase and choosing the material based on usage and personal aesthetic preferences.

Durability depends on the material and usage. A calf leather strap with vegetable tanning, subject to moderate wear, maintains functional and aesthetic integrity for 3-5 years. Alligator, being more resistant, can last 5-7 years. Factors such as humidity, frequency of use and UV exposure influence ageing. Leather that patinas is leather that lives; structural cracks require replacement.
