The Heritage

The Breitling Chronomat Evolution A1335611/A653 is a 43.70 mm stainless steel chronograph born in the 1980s as the official timepiece of the Italian Air Force's Frecce Tricolori aerobatic team. The Evolution variant introduced in 2004 maintains the iconic Rider Tabs, Rouleaux bracelet, and bidirectional rotating bezel. It features the Breitling 13 automatic chronograph movement with vertical column mechanism, COSC-certified to ±4 seconds per day, and offers 200-meter water resistance. The 20 mm lug width accommodates quality aftermarket straps without modification.

FAQ

What is the lug width of the Breitling Chronomat Evolution A1335611/A653?

The lug width of the Breitling Chronomat Evolution A1335611/A653 is exactly 20mm, measured at the innermost point between the lugs, flush against the case. Despite the generous 43.70mm case diameter, the signature Rider Tabs on the bezel alter the visual perception of the overall size, making the 20mm lug width entirely coherent with the model's architectural proportions.

What is the best strap for the Breitling Chronomat Evolution A1335611/A653?

The answer depends on intended use and dial colour. For formal occasions, an alligator strap paired with a brushed steel deployante clasp enhances the case's premium character. For daily dynamic wear, vegetable-tanned calfskin in cognac or black develops a personal patina over time. Shell cordovan is the preferred choice for those seeking moisture resistance and longevity without sacrificing leather aesthetics. For sporting or marine use, a vulcanised rubber strap is the most functional option.

How do you change the strap on the Breitling Chronomat Evolution A1335611/A653?

The Chronomat Evolution is fitted with an integrated Rouleaux bracelet with standard 20mm lugs. To replace it with an aftermarket strap, remove the original bracelet using a proper springbar tool, applying gentle pressure at the dedicated recesses on the lugs. It is advisable to work on a soft cushion to avoid scratching the case. Standard 20mm springbars are fully compatible. The operation is fully reversible and does not require a watchmaker's intervention.

Are there aftermarket straps compatible with the Breitling Chronomat Evolution A1335611/A653?

Yes. The standard 20mm lug width ensures full compatibility with the entire range of aftermarket straps available for this size. Milano Straps and the Casati Milano atelier produce bespoke handcrafted straps specifically designed for this reference, with shaped lug profiles tailored to the Chronomat case geometry. The selection includes alligator, calfskin, shell cordovan, rubber and nylon NATO straps.

How long does a leather strap last on a Breitling Chronomat Evolution A1335611/A653?

The lifespan of a leather strap depends on the material, care and frequency of use. A vegetable-tanned calfskin strap, worn daily and rotated with other straps, typically lasts between 18 and 36 months before showing significant wear. Shell cordovan, thanks to its compact, non-porous structure, can comfortably reach 4 to 5 years with routine maintenance. Straps produced by Casati Milano carry an 18-month warranty against manufacturing defects.
