Frequently asked questions

What is the lug width of the Breguet Classique 7800BA/11/9YV?

The Breguet Classique 7800BA/11/9YV is fitted with an 18mm lug width. This is the measurement to use when selecting any compatible strap, whether leather or other materials. For accurate verification, measure with a caliper inside the two lugs of the case.

What is the best strap for the Breguet Classique 7800BA/11/9YV?

For the yellow gold case and guilloché dial, the ideal strap is Louisiana alligator in semi-gloss cognac or burgundy tone. The scaled grain visually complements the engraved dial texture. For a custom strap with shaped attachment on the integrated lug, Casati Milano's service is the most accurate solution.

How do you change the strap on a Breguet Classique 7800BA/11/9YV?

The change requires a fine-tipped precision spring bar tool to avoid scratching the yellow gold lugs. It is advisable to rely on a watchmaker or specialized atelier such as Casati Milano, especially if the original strap is integrated with curved ends requiring a custom-shaped strap.

Are there aftermarket straps compatible with the Breguet Classique 7800BA/11/9YV?

Yes. All straps with 18mm attachment are technically compatible. A selection of 18mm straps in various materials and finishes is available on milanostraps.it. For a result aesthetically consistent with the integrated case, it is advisable to request a strap with curved or shaped ends.

How long does a leather strap last on a Breguet Classique 7800BA/11/9YV?

A quality leather strap — alligator or box-calf — has an average lifespan of 18–36 months with regular use, varying based on exposure to sweat, humidity, and heat. Casati Milano artisanal straps are covered by an 18-month warranty against manufacturing defects and develop a personal patina over time that enhances their character.
