Breguet
Classique 7787BB/12/9V6— lug 18mm

The Breguet Classique 7787BB/12/9V6 is fitted with an 18mm lug width at the junction with the case. To confirm the measurement on your own watch, measure the distance between the two lugs with a digital caliper at the narrowest attachment point, excluding the tapered section of the original strap.

For a Classique in white gold with a guilloché dial, a polished black or midnight blue alligator strap with a white gold buckle represents the most stylistically coherent choice. Alternatively, box calf leather in burgundy or light tobacco offers a refined and soft aesthetic for business-formal settings. Casati Milano creates bespoke straps calibrated to the specific lugs of this reference.

Strap replacement is performed using the spring bars that connect the strap to the lugs of the white gold case. A dedicated spring bar tool is used to release the bars. Given the delicate nature of the white gold lugs, it is recommended that you have this operation performed by a watchmaker or specialized atelier such as Casati Milano to avoid scratching the case.

Yes, all 18mm straps with standard spring bar attachments are technically compatible with the Breguet Classique 7787BB/12/9V6. A selection of artisanal 18mm straps designed for high-end dress watches is available at milanostraps.it. For optimal fit, Casati Milano also offers custom-made straps with end curvature adapted to the specific geometry of this model's lugs.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear, and exposure to perspiration and humidity. Manufacturing-grade alligator on a dress watch, worn intermittently and stored properly, maintains structural and aesthetic integrity for 3 to 5 years. Casati Milano straps are covered by an 18-month warranty against manufacturing defects and are crafted from premium leathers selected to maximize longevity.
