Strap for Elite Classic 40 Stainless Steel / Blue

The lug width of the Zenith Elite 03.3100.670/02.C922 is 22mm. This measurement, determined by the pin seats on the case, is constant across all examples of this model. To verify strap compatibility, measure the distance between the centres of the holes where the spring bars are seated: it must be exactly 22mm.

Alligator is the most refined choice: the geometric grain of the scutellum creates sophisticated contrast with the brushed steel case surface. Vegetable-tanned calf is an elegant alternative and develops a natural patina over time that mirrors the steel's evolution. Shell cordovan is ideal for those who appreciate slow leather maturation and desire chromatic depth as the piece ages.

To change the strap, you must remove the spring bars from the case seats using a dedicated tool (spring bar tool). The original pins can be transferred to a new universal 22mm strap, or a new custom strap can be crafted with pre-cut pin seats matching your original bars. For delicate operations, consultation with a qualified watchmaker or the Casati Milano atelier is recommended to ensure micrometric precision.

All universal 22mm straps are compatible with the 03.3100.670/02.C922, provided the lug bar seats align with the case width. On milanostraps.it you will find a curated selection of straps in alligator, calf, vegetable-tanned leather, shell cordovan, and rubber, specifically engineered for this size. The Casati Milano atelier additionally crafts bespoke custom straps personalised for your timepiece.

Durability depends on leather quality and usage conditions. A high-quality alligator or shell cordovan strap, properly maintained, guarantees 5-10 years of regular wear. Vegetable-tanned calf has comparable longevity, with the advantage of an aesthetic patina that improves with time. The standard warranty on Casati Milano custom straps is 18 months, covering manufacturing defects and premature wear from production imperfections.
