Strap for Tourbillon Five Days Platinum / Silver / Bracelet

The Breguet Classique Complications 5317PT/12/PV0 is fitted with an 18mm lug width, a standard measurement maintained consistently across the entire Classique line. To verify on your own example, it is advisable to measure with a digital caliper the internal distance between the two lugs at the narrowest point, adjacent to the case.

For this platinum model with a guilloché enamel dial, a genuine alligator strap represents the most coherent choice. Alligator grain — polished smooth or matte — complements the artisanal dial work and respects the formal vocation of the piece. A polished black or midnight blue alligator enhances the sobriety of the platinum case, while cognac or tobacco introduces chromatic warmth without compromising elegance.

The strap is replaced by acting on the spring bars that secure the strap to the case lugs. A dedicated spring bar tool or lever is required, inserted into the lateral hole of the lug to compress and remove the bar. On a platinum piece such as the 5317PT/12/PV0, it is recommended to entrust the operation to a watchmaker or use tools with coated tips to avoid scratches on the lugs.

Yes. Any strap with an 18mm attachment and a straight or slightly tapered profile is compatible. Milano Straps offers a selection of artisanal 18mm straps — in alligator, box-calf leather, and other hides — crafted with specifications designed for Breguet Classique watches. It is important to verify that the strap end is compatible with the profile of the slightly concave lugs typical of this family.

The lifespan of a leather strap depends on the quality of the hide, frequency of use, and exposure to perspiration and humidity. A high-quality alligator strap, used with care and stored correctly, can last between 2 and 5 years while maintaining a dignified patina. Casati Milano artisanal straps are covered by an 18-month warranty against manufacturing defects, with reinforced stitching and hides selected from certified tanneries.
