Strap for Classique 7337 White Gold / Silver

The Breguet Classique 7337BB/12/9VU features lugs with a nominal width of 18mm, measured internally between the two lugs at the junction point with the case. This is the standard measurement adopted by Breguet across the entire 39mm Classique family. To verify it on your own example, it is recommended to measure with a vernier caliper after removing the original strap.

For the white gold case and guilloché dial of the 7337BB, the best pairing is a Nile alligator strap with fine grain and polished finish, in midnight blue or burgundy coloring. Alternatively, polished black box calf leather offers absolute formal elegance with a patina that improves over time. The buckle should be in steel or rhodium-plated, never yellow gold, to maintain chromatic coherence with the white gold case.

The strap is removed via special spring bars housed in the lugs. It is recommended to use a flat-tipped tool or a professional spring bar remover, working on a padded surface to protect the white gold case from scratches. Given the preciousness of the material, it is preferable to entrust the operation to a watchmaker or a specialized atelier such as Casati Milano, which performs strap mounting with every order.

Yes, any strap with an 18mm attachment is technically compatible with the Breguet Classique 7337BB/12/9VU. Milano Straps offers a selection of artisanal 18mm straps made in Italy, with materials and finishes appropriate to the caliber of the timepiece. For a completely personalized solution, Casati Milano creates bespoke straps by selecting the leather directly in the atelier.

The lifespan of a leather strap depends on the material, care, and daily use. A quality alligator, if kept away from water and excessive sweating and periodically treated with specific products, maintains structural integrity and appearance for 3-5 years of regular use. Box calf leather develops a characteristic patina over time but is more sensitive to moisture. Casati Milano offers an 18-month warranty against manufacturing defects on all straps produced.
