Strap for Classique Perpetual Calendar 7327 White Gold / Silver

The Breguet Classique Complications 7327BB/11/9VU is fitted with an 18mm lug width. This measurement is taken with a digital caliper positioned between the two lugs at the internal spring bar seat. All 18mm straps from Milano Straps are compatible with this reference.

For the rose gold case of the 7327BB/11/9VU, an alligator strap with matte or polished finish in cognac, tobacco, or midnight blue tones is the most fitting choice, complementing the dressy character of the guilloché dial. A box calf leather develops a personal patina over time that is equally appreciated. A rose gold deployant or pin buckle completes the pairing with aesthetic rigor.

The strap is removed by carefully leveraging the spring bars that connect the strap to the case lugs. It is essential to use a dedicated spring bar fork tool, preferably with a coated tip to avoid scratching the rose gold lugs. This operation requires care: for cases in precious metals, it is advisable to entrust the work to a watchmaker or Casati Milano service.

Yes. Any strap with an 18mm lug width is technically compatible with the Breguet 7327BB/11/9VU. Milano Straps offers a selection of handcrafted 18mm straps made from carefully selected leathers — alligator, calf, ostrich leather — with customizable finishes and stitching to respect the aesthetic standard of a haute horlogerie timepiece.

The lifespan of a leather strap depends on the leather type, care, and frequency of use. Quality alligator, treated with appropriate products and not exposed to water or heavy perspiration, maintains structural and aesthetic integrity for 3-5 years with regular wear. Calf leather tends to develop a patina more quickly but can last just as long if properly maintained. Milano Straps warrants its 18mm straps for 18 months against manufacturing defects.
