Strap for Classique Double Tourbillon Quai de l'Horloge

The Breguet Classique Complications 5345PT/1S/7XU is fitted with a 20mm lug width. This is the internal distance between the two lugs at the strap attachment point. To confirm the measurement on your specific watch, it is recommended to verify it with a caliper after removing the strap.

For a platinum case with tourbillon movement, smooth alligator leather in matte or semi-gloss grain finish is the most appropriate choice for the formal character of this piece. The most suitable colors are slate gray, midnight blue, and tobacco brown. A butterfly deployant buckle in platinum or brushed titanium completes the pairing while protecting the strap from daily wear.

Strap replacement is performed using a fine-tipped spring bar tool, inserting the tool into the lateral hole of the lug to compress the spring-loaded pin and release the strap. On a platinum case, it is recommended to protect the surfaces with masking tape during the operation to avoid micro-scratches. Alternatively, the service can be performed at the Casati Milano atelier by appointment.

Yes. Any strap with a 20mm lug width is technically compatible with the Breguet Classique Complications 5345PT/1S/7XU. Milano Straps offers a selection of handcrafted 20mm straps in alligator, calf, and other materials, finished and constructed to standards comparable to major Swiss watchmaking manufacturers.

The lifespan of a leather strap depends on daily use, exposure to perspiration and humidity, and leather quality. A high-quality alligator strap, worn with alternation and properly stored, maintains its structural and aesthetic qualities for 2-4 years. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
