Breguet
Classique Complications 5359BB/6B/9V6/DD0D— lug 20mm

The Breguet Classique Complications 5359BB/6B/9V6/DD0D is fitted with 20mm lug width straps at the case attachment. This is a standard measurement in haute horlogerie dress watches, compatible with the extensive range of artisanal 20mm straps available on milanostraps.it.

For this white gold tourbillon with slate dial, the most suitable strap is midnight blue or black alligator belly-cut leather with a white gold buckle. Alternatively, box-calf veal with natural patina in cognac or burgundy offers a more understated and personal elegance, perfect for a dress watch of this caliber.

The strap is removed and replaced via standard spring bars housed in the lugs. A fine-pointed spring bar tool is sufficient to compress the bars without scratching the white gold case. The operation takes just a few minutes and can be performed independently or entrusted to a watchmaker or the Casati Milano atelier.

Yes. Any strap with 20mm lugs and standard spring bars is technically compatible. Milano Straps offers a selection of artisanal 20mm straps in alligator, calf leather, and other premium materials, crafted with bespoke finishes to respect the aesthetics of grand complication watches like this Breguet.

Durability depends on the material and daily use. A quality alligator strap, with proper maintenance and rotated wear, typically lasts between 2 and 4 years before showing significant signs of wear. Box-calf veal develops an elegant patina over time but is more sensitive to humidity. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
