Strap for Classique Tourbillon 5367 Platinum / Blue

The Breguet Classique Complications 5367PT/2Y/9WU is fitted with an 18mm lug width. This measurement is verified with a graduated caliper by measuring the internal distance between the two lugs at the narrowest point, where they contact the case.

For a rose gold tourbillon with a guilloché dial, a polished alligator strap remains the most coherent choice: the natural grain of the scales visually complements the dial finishing. Alternatively, smooth calf leather in cognac or burgundy offers a more everyday aesthetic with a patina that improves over time.

The replacement is done using traditional spring bars housed in the lugs. It is advisable to use a dedicated lever screwdriver with a rounded tip to avoid scratching the rose gold case. For watches of this caliber, it is recommended to entrust the work to a watchmaker or a specialized atelier such as Casati Milano.

Yes. Any strap with an 18mm attachment is technically compatible. Milano Straps offers a selection of artisanal 18mm straps in alligator, calf, and other leather, crafted with custom-fitted buckles and keepers suited to the haute horlogerie aesthetic of the Classique Complications.

The lifespan depends on the type of leather and usage. A quality alligator strap, kept away from water and perspiration and rotated regularly with other straps, can last three to six years while maintaining structural integrity. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
