Strap for Tourbillon Five Days Rose Gold / Silver

The Breguet Classique Complications 5317BR/12/9V6 is fitted with an 18 mm lug width. This measurement is verified by placing a millimeter ruler between the two lugs on the top side of the case: the internal distance should be exactly 18 mm. All straps with 18 mm attachment are compatible with this reference.

For a rose gold tourbillon such as the 5317BR/12/9V6, mississippi alligator in large grain with polished finish is the choice most consistent with the watch's neoclassical aesthetic register. Alternatively, smooth polished box-calf leather in tobacco brown, cognac, or bordeaux enhances the guilloché dial without diverting attention from the complication. Casati Milano crafts both options bespoke for this specific reference.

The strap is removed using a spring bar tool with a fine point, inserting the tip into the spring bar seat and compressing the spring until it releases. The operation requires care to avoid scratching the rose gold lugs: it is recommended to position the watch on a soft cushion and use a tool with a nylon-coated tip. In case of doubt, a trusted watchmaker can perform the replacement in a few minutes.

Yes. Any strap with an 18 mm attachment is technically compatible with the 5317BR/12/9V6. Milano Straps offers a selection of artisanal 18 mm straps in alligator, calf, and other fine materials, crafted with spare spring bars included. Casati Milano also provides a bespoke service with leather selection in-atelier for those seeking a strap constructed specifically around the proportions and colors of this reference.

Longevity depends on the material, frequency of use, and care. A superior quality alligator strap, worn in rotation with other watches and kept away from excessive water and perspiration, maintains structural and aesthetic integrity for 3-5 years or more. Box-calf leather has comparable longevity but develops a patina of use more quickly. Milano Straps guarantees its 18 mm straps for 18 months against manufacturing defects, regardless of material chosen.
