Strap for Chronomat Evolution Stainless Steel / Yellow Gold / Blue

The lug width of the Breitling Chronomat Evolution B1335611/C646 is 20mm. This measurement is taken internally between the two lugs of the case using a digital calliper, and represents the exact reference for selecting a compatible strap.

For the two-tone steel and yellow gold Chronomat Evolution, an alligator strap with vegetable tanning in tobacco or dark brown is the most harmonious choice: the bombé grain complements the case geometry and tempers the sporty character with a sartorial note. Black smooth calfskin or a NATO strap are strong alternatives for more active settings.

The strap is replaced by removing the spring bars connecting it to the case lugs. A spring bar tool is used to compress the pins and slide the strap free without risking scratches to the case. The operation takes approximately two minutes and does not require watchmaker intervention.

Yes. Any strap with a 20mm lug width and standard spring bar fitting is compatible with the Chronomat Evolution B1335611/C646. Milanostraps.it offers a curated selection of handcrafted 20mm straps in various materials, available bespoke or ready for immediate dispatch.

The lifespan of a leather strap depends on the material and frequency of use. A quality vegetable-tanned alligator strap, with regular maintenance (cleaning and conditioning), typically lasts between three and five years with daily wear. Calfskin straps have a shorter cycle but are more economical to replace. Casati Milano straps include an 18-month warranty against manufacturing defects.
