Breguet
Classique Complications 7637BB/2Y/9ZU— lug 20mm

The Breguet Classique Complications 7637BB/2Y/9ZU is fitted with a 20mm lug width. This measurement should be taken with a digital caliper inside the case lugs, at the strap attachment point, and not on the mounted strap.

For this model in white gold with guilloché dial, the ideal strap is Mississippiensis alligator with a semi-gloss finish — preferably in midnight blue, tobacco brown, or slate gray. The regular grain of the ventral scales harmonizes beautifully with the dial decoration. Alternatively, box calf leather is suitable for a more sober and formal look.

The strap is replaced using a fine-tipped springbar tool, leveraging the springbar ends inside the lug. On an 18k white gold case, it is essential to use a tool with a plastic or coated tip to avoid scratches. If you lack experience, it is advisable to entrust it to a watchmaker or the Casati Milano atelier service.

Yes, any strap with a standard 20mm attachment is compatible with the Breguet Classique Complications 7637BB/2Y/9ZU. Milano Straps offers a selection of artisanal 20mm straps in various materials and colors, made to order or available ready online, with heel thickness calibrated to guarantee optimal fit on classic cases.

The lifespan of a leather strap depends on the quality of the leather, the wearer's care, and the frequency of use. An artisanal-quality alligator or calf strap, kept away from water and excessive sweat and treated periodically with nourishing cream, can last from 3 to 7 years while maintaining a charming aged patina. Casati Milano guarantees its straps for 18 months against manufacturing defects.
