Strap for Chronomat Evolution Stainless Steel / Yellow Gold / Silver

The lug width of the Breitling Chronomat Evolution B1335611/G570 is 20 mm. This measurement refers to the internal space between the two lugs and should be taken with a digital calliper. This standard size provides access to a wide range of quality aftermarket straps.

For the two-tone steel and yellow gold Chronomat Evolution, the most suitable options are a hornback alligator strap in cognac brown or matte black — ideal for complementing the bi-material case — or a vegetable-tanned calf leather strap for a more sport-tailored register. Vulcanised rubber is recommended for marine environments or intense physical activity.

Removing the original Rouleaux bracelet requires a specific bracelet screw tool. To fit a standard 20 mm aftermarket strap with spring bars, use a fine-tipped springbar tool. It is advisable to work on a soft surface to prevent accidental scratching of the yellow gold case components.

Yes. Any strap with a 20 mm attachment and standard spring bars is compatible with the Breitling Chronomat Evolution once the Rouleaux bracelet has been removed. Milano Straps offers a curated selection of handcrafted leather, rubber, and nylon straps specifically suited to the proportions of the 43.70 mm case.

A quality leather strap on a Chronomat Evolution typically lasts between 18 and 36 months with regular wear, depending on care, exposure to perspiration and moisture, and the type of leather used. Alligator and shell cordovan straps, owing to their denser fibre structure, tend to last longer and develop a distinguished aged patina. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
