Strap for Classima Automatic 40 Stainless Steel / Silver / Bracelet

The Classima 10215 features a lug width of 16mm. This measurement is precise and must be respected when selecting a compatible strap. You can verify it by measuring the linear distance between the internal gaps of the two lugs.

For the Classima 10215, we recommend alligator in vegetable tanning or shell cordovan, which enhance the pure aesthetics of the case without competing visually. Calf leather is a versatile choice for daily wear. For those preferring durability, a cotton NATO or sports rubber transform the watch into a more casual instrument.

Use a spring bar tool to gently extract the metal studs (spring bars) from the lugs. Position the tool in the spring groove, press lightly and withdraw the stud. Repeat for the other lug. Insert the new strap, aligning the holes with the lugs and re-press the spring bars until they click into place.

Yes, any strap with a 16mm lug width is compatible. Milanostraps offers a curated collection of 16mm straps made from premium leather and customisable according to your preferences for length, initials and thread colour.

A quality leather strap (alligator, cordovan, vegetable-tanned calf) typically lasts 3-5 years with balanced daily use. Longevity depends on maintenance, water exposure and leather quality. Vegetable-tanned leather develops patina over time, improving aesthetic appeal. Milanostraps provides an 18-month warranty on straps made by Casati Milano.
