Breguet
Classique 7337BB/Y5/9VU— lug 18mm

The Breguet Classique 7337BB/Y5/9VU is fitted with an 18mm lug width strap. This measurement is taken between the two lugs of the white gold case using a digital caliper, or by checking the width of the original Breguet strap at its attachment point to the case. It is the standard size adopted by Breguet across the entire 39mm Classique line.

The strap most consistent with the aesthetics of the 7337BB/Y5/9VU is alligator with Hornback grain in midnight blue or antique burgundy, featuring tone-on-tone stitching and a white gold deployant clasp. Box Calf leather that develops patina is a refined alternative for daily wear. Both materials respect the dress watch vocation of the model and complement the guillochéd dial and steel blue hands.

The strap on the Breguet Classique 7337BB/Y5/9VU is removed using a fine-pointed spring bar tool, applying leverage to the spring bars that hold the strap between the lugs. The Classique lugs are short and slightly curved, so it is advisable to entrust the work to a watchmaker or specialized atelier such as Casati Milano to avoid scratching the white gold case. Installing the new strap requires 18mm standard-length spring bars.

Yes, there are high-quality aftermarket straps compatible with the Breguet Classique 7337BB/Y5/9VU. It is necessary to choose straps with 18mm lugs, a soft body and tapered design toward the clasp, capable of adapting to the curved geometry of the Classique lugs. Milano Straps offers a selection of hand-crafted 18mm straps in alligator and calf leather, with the option of choosing custom work signed by Casati Milano.

The lifespan of a leather strap on a Breguet Classique 7337BB/Y5/9VU depends on the quality of the tanning and daily use. A-grade alligator or hand-worked Box Calf typically lasts between 2 and 4 years with regular wear, developing a characteristic patina over time. Exposure to sweat, water, and perfumes accelerates deterioration: it is advisable to alternate at least two straps and periodically treat the leather with neutral, purpose-made products.
