Breguet
Classique 7137BR/15/9VU— lug 18mm

The Breguet Classique 7137BR/15/9VU is fitted with lugs with a width of 18 mm. To verify compatibility with an aftermarket strap, measure with a digital caliper the internal distance between the two lugs at the bottom of the case: the value must be 18 mm with a tolerance of ±0.2 mm.

For the Classique 7137BR/15/9VU in rose gold, a Louisiana alligator or semi-polished hornback strap in cognac brown, havana or bottle green shades represents the most coherent choice with the watch's aesthetics. Alternatively, box-calf leather in midnight blue or bordeaux offers compact grain and impeccable formality. Vulcanized micro-grain rubber is recommended for intensive daily use.

The strap on the Breguet Classique 7137BR/15/9VU is replaced using a dedicated springbar tool, inserting the tip into the lateral eyelets of the lugs to release the 18 mm spring bars. It is advisable to entrust this to a watchmaker or specialized atelier such as Casati Milano to avoid scratches on the 18-carat rose gold case.

Yes, all straps with standard 18 mm attachment are compatible with the Breguet Classique 7137BR/15/9VU. On milanostraps.it a wide selection of 18mm straps is available in various materials and colors. For optimal fit, Casati Milano creates custom straps with shaped ends to follow the curved profile of the Classique's lugs.

The lifespan of a leather strap depends on the material and daily use. A quality alligator strap, with moderate use and proper storage away from moisture and perfumes, lasts on average 2 to 4 years before showing significant signs of wear. Box-calf leather has a similar lifespan but is less water resistant. Casati Milano offers an 18-month warranty on manufacturing defects on all handcrafted straps.
