Breguet
Classique 5719PT/US/9ZV/DD0D— lug 18mm

The Breguet Classique 5719PT/US/9ZV/DD0D is fitted with an 18mm lug width. This measurement is taken by inserting a caliper between the two lugs at the point where the strap is seated. The width at the strap end (toward the buckle) is typically 16mm or 14mm, depending on the chosen strap model.

For the Classique 5719 in platinum, an alligator strap is the most coherent choice with the watch's identity: the scaled grain visually complements the hand-guillochéd dial. A midnight blue or cognac brown alligator in polished or semi-matte finish enhances the cool neutrality of platinum. Box calf is a valid alternative for those preferring a slimmer profile under the cuff.

The strap is replaced using a spring bar tool or small flathead screwdriver, by prying the spring bar that connects the strap to the lugs. It is recommended to entrust this operation to a watchmaker or authorized dealer, particularly on a platinum case where scratches on the lugs are difficult to repair. Some ateliers, including Casati Milano, offer this service concurrently with delivery of a custom strap.

Yes. Any strap with an 18mm attachment and standard spring bar is technically compatible with the Breguet Classique 5719PT/US/9ZV/DD0D. The standard length (approximately 115mm/75mm for a 46mm case) should be verified based on wrist circumference. On milanostraps.it you will find a selection of compatible 18mm artisanal straps, with the option for bespoke customization through the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the tanning, frequency of use, and exposure to sweat and humidity. A high-quality alligator strap, with waxed thread stitching and well-finished edge binding, can last three to five years with regular use. A well-tanned box calf has similar durability but requires greater attention to moisture. Casati Milano guarantees 18 months against manufacturing defects on all straps produced in-house.
