Breguet
Classique 7787BB/29/9V6— lug 18mm

The lug width of the Breguet Classique 7787BB/29/9V6 is 18mm. This is the measurement to use when selecting a compatible strap. The width may taper toward the buckle, typically to 16mm, but the relevant measurement for purchase is always taken at the lug attachment point.

For the Classique 7787BB/29/9V6 in white gold, a matte or semi-polished mississippiensis alligator strap is the most appropriate choice, consistent with the watch's formal register and guilloché dial aesthetic. Recommended colors: midnight blue, anthracite gray, or cognac. Box calf represents a more understated alternative that develops a beautiful patina over time.

Strap replacement requires a fine-tipped spring bar tool to remove the attachment bars without scratching the white gold case. It is recommended to work on a soft surface with the case resting on the dial protected by a microfiber cloth. If in doubt, it is best to consult a qualified watchmaker or the Casati Milano atelier, which offers the service by appointment.

The lifespan of a leather strap depends on the material, care, and frequency of use. High-quality alligator, treated with protective cream and kept away from prolonged moisture, can last between 3 and 5 years while maintaining full structural integrity. Box calf tends to develop a characteristic patina but is more sensitive to water. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
