Strap for Chronomat Evolution Stainless Steel / Yellow Gold / MOP

The lug width of the Breitling Chronomat Evolution B1335611/A571 is 20mm. This measurement is taken between the two lugs at the base of the case and is the key specification for selecting a compatible replacement strap.

For the Chronomat Evolution B1335611/A571, with its two-tone steel and yellow gold case and mother-of-pearl dial, the most coherent choices are vegetable-tanned alligator belly in tobacco or midnight blue, cognac shell cordovan, or black vulcanised rubber for sporting use. A deployant clasp in steel or yellow gold PVD completes the pairing.

The strap on the Chronomat Evolution B1335611/A571 is secured by standard 20mm spring bars, removable with a dedicated springbar tool or Y-tip screwdriver. Work on a soft surface to prevent case scratches and take care near the lugs, which on this model are adjacent to the bezel rider tabs.

Yes. Any strap with a 20mm attachment width is technically compatible with the Chronomat Evolution B1335611/A571. Milano Straps offers a curated range of handcrafted leather, rubber and nylon straps sized specifically for 43–44mm sport cases, available with curved or straight ends depending on aesthetic preference.

The lifespan of a leather strap on the Chronomat Evolution B1335611/A571 depends on the material and frequency of wear. A quality vegetable-tanned alligator strap, worn on rotation, can last between three and five years. Shell cordovan, owing to its dense fibre structure, tends to last longer whilst developing a distinctive patina. Prolonged exposure to perspiration and water is the primary cause of deterioration; a rubber strap is recommended for intensive sporting use.
