Breguet
Classique 5707BB/12/BV0— lug 18mm

The Breguet Classique 5707BB/12/BV0 is fitted with an 18 mm lug width. This measurement should be taken with a digital caliper directly between the case lugs, regardless of the taper of the original strap.

For a white gold case with a guilloché dial, an alligator strap with a polished finish — in midnight blue or ardoise — is the most coherent choice with the watch's aesthetic register. Box calf leather is the most discreet alternative and capable of developing a unique patina over time.

The strap is replaced using a flat-tip or fork spring bar tool, by leveraging the spring bar that connects the strap to the lugs. On a white gold case, it is advisable to protect the surfaces with a soft cloth or dedicated pad to prevent scratches during the operation.

Yes. Any strap with an 18 mm lug width and standard spring bars is technically compatible. To respect the proportions of a Breguet Classique, it is essential to choose straps with proper taper — typically 18 to 16 mm — and materials of quality equal to the watch. Milano Straps offers a selection of 18mm artisanal straps designed for fine watchmaking.

A quality alligator or calf leather strap, with regular use, has an average lifespan of two to four years before wear and patina require replacement. Longevity depends on exposure to sweat, water, and UV light: storing the watch in its box when not worn and alternating multiple straps significantly extends the life of each piece.
