Strap for Chronomat Evolution Stainless Steel / Grey

The lug width of the Breitling Chronomat Evolution A1335611/E519 is 20mm. This measurement is taken with a digital calliper positioned internally between the two lower lugs of the case. This is the dimension to specify when purchasing any compatible aftermarket strap.

For the Chronomat Evolution A1335611/E519, the most suitable materials are hornback alligator for a sport-elegant aesthetic, shell cordovan for maximum durability and long-term patina development, and vegetable-tanned calf leather for everyday versatility. For a fully sporting option, vulcanised rubber with a reticulated texture best reflects the model's technical DNA. A brushed steel butterfly deployant clasp is the recommended closure for all materials.

The strap is removed using a springbar tool — either a flat-tip or fork-style tool. The lugs on the Chronomat Evolution have a slight downward curve, so care should be taken not to scratch the stainless steel case during the operation. With the correct tool, the procedure takes under two minutes. If in doubt, the operation can be carried out by any watchmaker or by the Casati Milano atelier.

Yes. The Chronomat Evolution A1335611/E519 features standard 20mm lugs, compatible with a wide range of quality aftermarket straps. Milanostraps.it offers options in alligator, shell cordovan, calf leather, NATO fabric and rubber, all crafted with ends shaped to accommodate the characteristic curved lug geometry of Breitling cases. It is essential to confirm that the chosen strap supports this curvature to ensure a correct, tension-free fit.

The lifespan of a leather strap depends on the material and frequency of wear. A vegetable-tanned calf leather strap worn regularly typically lasts 18 to 36 months. Alligator leather, owing to its compact fibrous structure, can last well over 3 to 5 years with proper care. Shell cordovan is notably the most durable of smooth leathers, often exceeding 5 years under normal conditions. All Casati Milano straps carry an 18-month manufacturing defect warranty.
