Breguet
Classique 7337BR/15/9VU— lug 18mm

The Breguet Classique 7337BR/15/9VU is fitted with an 18mm lug width. To verify before purchasing a replacement strap, measure with a digital caliper the distance between the two lugs on the dial side, not the outer diameter of the case.

For the 39mm rose gold case and enameled guilloché dial, the most suitable strap is Mississippiensis alligator with hornback grain, in bordeaux, mahogany, or midnight blue tones. Polished box calf is a formal alternative with evolving patina. Both respect the aesthetic DNA of the Classique without overwhelming the dial decoration.

The strap is replaced using a lever spring bar tool or fine-pointed pin, sliding the spring bars out from the case lugs. It is recommended to work on a soft surface to protect the rose gold case and to avoid lateral force to prevent scratches on the worked bezel. If in doubt, it is best to rely on a watchmaker or the Casati Milano atelier.

Yes, all straps with standard 18mm attachment are technically compatible with the 7337BR/15/9VU. Milano Straps offers a selection of handcrafted straps in leather and alternative materials specific to 18mm lugs, including bespoke models made by Casati Milano with attachment geometry adapted to the concave profile of Breguet lugs.

A quality leather strap — alligator or vegetable-tanned calf — on a daily-wear Breguet Classique typically lasts between 18 to 36 months, depending on exposure to sweat and humidity. Longevity increases significantly with rotation among two or three straps and periodic application of nourishing cream specific to fine leather. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
