Ostrich 21mm — Texture that ages with you

SIZE 21MM · OSTRICH

Deep grain and natural strength for those who don't choose the ordinary

Ostrich leather at 21mm requires precise craftsmanship: each stitch must follow the irregular grain without damaging it. The three-dimensional texture withstands daily use well and develops a patina over time. It's not as delicate as it seems—it's surprisingly robust, perfect for those who want visible personality on their wrist.

It pairs well with both sports watches and dress watches with 21mm lugs. In the atelier, we measure the watch together to perfectly fit the strap. Casati Milano offers custom cuts with handmade finishes that enhance the characteristic grain. Come and choose your leather in person.
