FAQ

What is the lug width of the Breguet Classique 5157BA/11/9V6?

The Breguet Classique 5157BA/11/9V6 is fitted with an 18mm lug width. This measurement is determined by the proportion of the 38mm yellow gold case and represents the standard size to specify when purchasing any compatible replacement strap.

What is the best strap for the Breguet Classique 5157BA/11/9V6?

For this yellow gold reference with guillochè dial, an alligator belly or hornback strap represents the most coherent choice with the manufacture's DNA. Cognac, bordeaux, or midnight blue tones enhance the yellow gold case without overpowering it. Smooth calf leather in black or chocolate brown is an elegant formal alternative. The 18mm straight lug is the technical parameter to respect.

How do you change the strap on the Breguet Classique 5157BA/11/9V6?

Strap replacement requires a spring bar tool to remove the fixing bars from the case lugs. It is recommended to work on a soft surface to protect the dial and yellow gold case. Alternatively, Casati Milano offers installation service at their Milan atelier by appointment, with the utmost care for the timepiece's surfaces.

Are there aftermarket straps compatible with the Breguet Classique 5157BA/11/9V6?

Milano Straps offers a selection of handcrafted 18mm straps in alligator, calf, and other materials, finished to suit a timepiece of this category.

How long does a leather strap last on a Breguet Classique 5157BA/11/9V6?
