Strap for Chronomat Evolution Stainless Steel / Yellow Gold / White - Roman

The lug width of the Breitling Chronomat Evolution C1335611/A619 is 20 mm. This measurement is taken using a millimetre calliper between the inner edges of the two lugs on the case. It is an essential specification for selecting a compatible strap that fits without lateral play or misalignment.

For a bi-material case in stainless steel and yellow gold such as the Chronomat Evolution C1335611/A619, a square-scaled alligator strap in cognac or gloss black is the most aesthetically coherent choice. Vegetable-tanned calf leather suits daily wear, developing an authentic patina over time. NATO or vulcanised rubber straps are recommended for sporting or marine environments.

The strap is removed using a fine-tipped spring bar tool, carefully depressing the spring bar that connects the strap to the case lugs. Work on a soft surface to avoid scratching the case and do not apply excessive force to the lugs. If in doubt, entrust the operation to a watchmaker or contact Casati Milano atelier for professional assistance.

Yes. Any strap with a 20 mm lug width is technically compatible with the Chronomat Evolution C1335611/A619, provided the end curvature suits the geometry of Breitling's lugs. Milano Straps offers a curated selection of handcrafted 20 mm straps — in alligator, calf leather, NATO and rubber — designed for precise fit and finish consistent with the watch's aesthetic.

The lifespan of a leather strap depends on leather quality, frequency of wear and exposure to perspiration and moisture. A high-quality alligator or calf leather strap with waxed-thread stitching and appropriate protective treatments can last between 2 and 5 years under regular use. Casati Milano's 18-month warranty covers manufacturing defects; actual longevity also depends on daily care and maintenance.
