FAQ

What is the lug width of the Breguet Classique 7337BA/1E/9V6?

The Breguet Classique 7337BA/1E/9V6 is fitted with 18mm lugs. This measurement is taken with a digital caliper across the internal distance between the two lugs at the point closest to the case. All 18mm straps are compatible with this reference.

What is the best strap for the Breguet Classique 7337BA/1E/9V6?

For a yellow gold case with a guilloché dial, the most coherent strap choice is Louisiana alligator with polished finish, ideally in midnight blue or havana brown. Box calf leather represents a more versatile everyday alternative, capable of developing patina over time and complementing the watch without overwhelming it.

How do you change the strap on a Breguet Classique 7337BA/1E/9V6?

The strap is removed using a dedicated spring bar tool inserted into the lateral channel of the lugs to release the spring bars. The operation takes only a few seconds but should be performed carefully on a soft surface to avoid scratching the gold case. In case of doubt, it is advisable to contact a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Breguet Classique 7337BA/1E/9V6?

Yes. Any strap with an 18mm lug width is technically compatible. Milano Straps offers a selection of artisanal 18mm straps crafted with carefully selected leather and custom finishes, specifically designed for fine watches such as the Breguet Classique.

How long does a leather strap last on a Breguet Classique 7337BA/1E/9V6?

Durability depends on the type of leather, daily use, and care. A quality alligator or calf leather strap, worn in rotation and kept away from excessive water and perspiration, maintains its structural and aesthetic integrity for 2-4 years. Casati Milano offers an 18-month warranty against manufacturing defects on all custom-made straps.
