Strap for Classique 7137 Yellow Gold / Silver

The Breguet Classique 7137BA/11/9V6 is fitted with an 18 mm lug width. This measurement is determined by the proportional relationship between the 39 mm case and the strap attachment, and can be verified with a digital caliper by measuring the internal distance between the two lugs at the point of contact with the strap.

For the 7137BA in yellow gold, smooth or semi-matte alligator is the choice most consistent with Breguet's formal code. Recommended colors are black for maximum contrast, cognac for a warm pairing with the gold case, or midnight blue to complement the blued gold pomme hands. Box-grain calf is a refined alternative for daily wear.

The strap is replaced using a fine-tipped spring bar tool, inserting the tool into the spring bar seat between the lugs and carefully levering to release one end first, then the other. On a yellow gold watch, it is advisable to protect the lug surfaces with thin fabric tape or entrust the work to a watchmaker or the Casati Milano atelier to prevent scratches.

Yes. Any strap with an 18 mm lug width and standard spring bars is technically compatible. On milanostraps.it you will find a selection of 18 mm straps in fine leather, hand-crafted, compatible with the Breguet Classique 7137BA/11/9V6 and available both online and customizable on request at the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the material, care, and frequency of use. A high-quality alligator strap, if kept away from excessive moisture and treated periodically with appropriate creams, can last between three to five years while maintaining good structural integrity. Casati Milano straps are made with carefully selected leather and hand-stitched, with an 18-month warranty against manufacturing defects.
