Frequently asked questions

What is the lug width of the Breguet Classique 5717BR/EU/9ZU?

The Breguet Classique 5717BR/EU/9ZU is fitted with an 18 mm lug width. This measurement should be taken with a caliper between the case lugs, not on the original strap which may have tapering or beveling that skews the reading.

What is the best strap for the Breguet Classique 5717BR/EU/9ZU?

An alligator Mississippiensis strap with square grain finish is the most coherent choice for the dress watch aesthetic of the Classique 5717 in rose gold. Deep burgundy or midnight blue on polished finish represent the most refined color combinations. Box calf leather is an excellent alternative for a more understated approach.

How do you change the strap on the Breguet Classique 5717BR/EU/9ZU?

The Classique 5717 is equipped with an integrated bracelet and specific Breguet attachment. To replace it with an aftermarket strap, a dedicated adapter or 1.8 mm compatible spring bars are required. The operation requires a flat spring bar tool and care to protect the rose gold finish on the case lugs from scratches.

Are there aftermarket straps compatible with the Breguet Classique 5717BR/EU/9ZU?

Yes. Aftermarket straps with standard 18 mm attachment are compatible with the Breguet Classique 5717BR/EU/9ZU through specific adapters for the house. Milano Straps offers a selection of 18mm straps in alligator, calf, and other materials crafted by artisans, with the option for bespoke customization through the Casati Milano atelier.

How long does a leather strap last on a Breguet Classique?

A quality leather strap — alligator or properly tanned calf — lasts between 2 and 4 years with regular use, depending on exposure to perspiration, humidity, and direct sunlight. Alligator tends to develop a patina that enhances its aesthetic value over time; calf shows signs of wear more quickly but is easily replaceable. Milano Straps warranty covers 18 months against manufacturing defects.
