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

The lug width of the Breitling Chronomat Evolution B1335611/B918 is 20 mm. This measurement is taken internally between the two lugs and determines compatibility with any aftermarket strap. It is advisable to verify this with a digital calliper before purchasing, as the muscular lug profile of this model requires a strap with appropriately shaped ends.

For the Chronomat Evolution B1335611/B918 in its two-tone yellow gold and stainless steel configuration, a tobacco brown alligator or vegetable-tanned calf strap is the most coherent choice: it balances the substantial case and enhances the chromatic contrast. For more sporting use, vulcanised rubber or ballistic nylon NATO straps are functional and stylistically appropriate alternatives.

Replacing the strap on the Chronomat Evolution requires a fine-tipped or forked spring bar tool to remove the spring bars housed within the lugs. It is advisable to work on a soft surface to protect the case. If replacing the original Rouleaux bracelet with a leather or rubber strap, it is recommended to entrust the operation to a watchmaker or specialist atelier to avoid scratching the gold or steel lugs.

It is essential to select straps with curved or semi-curved ends to properly fit the case profile.

The lifespan of a leather strap depends on the type of hide, frequency of wear, and exposure to perspiration and moisture. A quality alligator strap, worn with care and rotated with others, can last three to five years whilst retaining a presentable appearance. Vegetable-tanned calf, although less resistant to moisture, develops a distinctive patina over time that extends its aesthetic value. Using a deployant clasp reduces stress on the leather at the buckle hole, significantly increasing longevity.
