FAQ

What is the lug width of the Breguet Classique 5930BA/12/986?

The Breguet Classique 5930BA/12/986 is fitted with an 18 mm lug width. To verify this yourself, use a caliper to measure the internal distance between the two lugs on the case, excluding any stitching from the original strap that could affect the reading.

What is the best strap for the Breguet Classique 5930BA/12/986?

For a yellow gold Classique, artisanal alligator is the most coherent choice with the watch's identity: the natural grain of the leather echoes the guilloché work on the dial. The most suitable colors are dark chocolate, cognac with patina, and burgundy. Smooth calf leather in anthracite or tobacco represents a solid everyday alternative.

How do you change the strap on a Breguet Classique 5930BA/12/986?

The strap is removed using a spring bar tool, a pointed two-pronged instrument that levers the spring bars housed in the lugs. The operation requires care to avoid scratching the yellow gold case: it is recommended to consult a watchmaker or specialized atelier such as Casati Milano.

Are there aftermarket straps compatible with the Breguet Classique 5930BA/12/986?

Yes. Any strap with an 18 mm attachment is technically compatible with the Breguet Classique 5930BA/12/986. A selection of artisanal alligator and calf straps specifically suited to dress watches in this segment is available on milanostraps.it, with the option of bespoke customization through Casati Milano.

How long does a leather strap last on a Breguet Classique 5930BA/12/986?

A high-quality alligator or calf strap, if properly maintained — kept away from water, excessive perspiration, and direct sunlight — has an average lifespan of 2-4 years with daily use. Casati Milano straps are covered by an 18-month warranty against manufacturing defects. Proper rotation between two or three straps significantly extends their life.
