Strap for Classique 5140 Yellow Gold / Silver

The Breguet Classique 5140BA/12/9W6 is fitted with an 18mm lug width. This measurement can be verified with a digital caliper positioned between the two lugs at the junction point between the case and the first keeper of the original strap. All straps with 18mm attachment are compatible without modifications to the spring bars.

For the 18-carat yellow gold case, the most coherent strap is Hornback alligator in bordeaux or cognac: the grain of the crocodile back dialogues with the warm reflections of gold and recalls the neoclassical aesthetic of the guilloché dial. Alternatively, a dark brown smooth calf with glossy finish ensures formal correctness when paired with dark attire.

The Breguet Classique 5140BA/12/9W6 strap is secured with standard 18mm spring bars. Replacement requires a dedicated springbar tool with a fine tip: insert it into the lateral hole of the lug, compress the spring bar, and remove the strap. The operation takes approximately two minutes per side and does not require professional equipment, but it is advisable to work on a soft surface to protect the gold surfaces.

Yes. Any strap with 18mm attachment and standard length (typically 115/75mm or 120/80mm) is compatible with the Breguet Classique 5140BA/12/9W6. Milano Straps offers a selection of artisanal 18mm straps made in alligator, calf, and other fine materials, with deployant or pin buckles, suitable for the yellow gold case of this reference.

The lifespan of a leather strap depends on the material, daily care, and frequency of use. A quality alligator, kept away from prolonged moisture and periodically treated with specific nourishing cream, maintains structural and aesthetic integrity for three to five years with regular use. Milano Straps artisanal straps are covered by an 18-month warranty against manufacturing defects.
