Strap for Chronomat Evolution Stainless Steel / Black - Roman

The lug width of the Breitling Chronomat Evolution A1335611/B898 is 20 mm. This measurement is taken with a digital calliper positioned between the lower lugs of the case, against the inner surfaces. This is the figure required when ordering any compatible aftermarket strap.

For the Chronomat Evolution, a wide-grain alligator belly strap offers the most effective textural contrast against the 43.70 mm stainless steel case. Vegetable-tanned calfskin is preferable for intensive daily wear, developing a patina over time. Vulcanised rubber preserves the instrument character of the chronograph for sporting use. In all cases, the 20 mm lug width must be respected, and the taper of the strap should be proportional to the visual mass of the case.

Changing the strap on the Chronomat Evolution requires a spring bar tool with a fine tip. The case lugs are standard and accept 20 mm spring bars. It is advisable to work on a soft surface to avoid scratching the case. If the spring bars are worn or deformed, they should be replaced at the same time as the strap. For models fitted with the original Pilot bracelet, the bracelet must first be removed from the lugs using the appropriate link pins.

Yes. The standard 20 mm lug width ensures broad compatibility with aftermarket straps from any manufacturer. It is important to verify that the chosen strap has a taper appropriate to the 43.70 mm case and that the spring bars have the correct diameter (typically 1.8 mm). Milanostraps.it offers a curated selection of compatible 20 mm straps in artisanal leather and technical materials, crafted to order by the Casati Milano atelier.

The lifespan of a leather strap depends on the material and frequency of use. A quality vegetable-tanned calfskin strap, worn daily with proper care (periodic cleaning, leather-specific conditioner), can last between two and four years. Well-tanned alligator offers superior durability due to the compact structure of the hide. Casati Milano straps carry an 18-month warranty against manufacturing defects. Frequent exposure to water and perspiration accelerates deterioration; in such cases a rubber or NATO strap is recommended.
