Strap for Chronomat Evolution Stainless Steel - Diamond / MOP

The Breitling Chronomat Evolution A1335611/A570 features a 20mm lug width. This measurement refers to the internal distance between the two case lugs and determines compatibility with all 20mm aftermarket straps available on the market.

The choice depends on the intended context. For formal or business use, a vegetable-tanned alligator strap fitted with a stainless steel deployant clasp enhances the visual complexity of the dial. For sport or marine use, a vulcanised rubber strap in 20mm is the most technically appropriate solution, fully compatible with the model's 200-metre water resistance rating.

Strap replacement is carried out using standard 20mm springbars. A fine-tipped springbar tool is required to lever against the lug without scratching the case. Given the pronounced lug curvature of the Chronomat Evolution, straps with pre-curved or angled ends are recommended to ensure correct fitment and prevent undue stress on the springbar.

Yes. The Chronomat Evolution A1335611/A570 uses a standard 20mm lug attachment compatible with the full range of aftermarket straps for this width. Milano Straps and the Casati Milano atelier produce bespoke straps in alligator, vegetable-tanned calfskin, shell cordovan and technical rubber, with options to customise length, thickness and buckle type.

A quality leather strap, properly maintained, typically lasts between 2 and 4 years with daily wear. Longevity depends on the material: shell cordovan and vegetable-tanned alligator offer the highest abrasion resistance. Using a deployant clasp significantly reduces mechanical stress on the leather, extending the strap's service life. Casati Milano provides an 18-month warranty against manufacturing defects.
