Strap for Tourbillon Five Days Platinum / Silver

The Breguet Classique Complications 5317PT/12/9V6 comes with a strap featuring an 18 mm lug width. This measurement is binding: a strap of a different size will not fit correctly between the lugs of the platinum case without compromising the aesthetics and the strap's grip on the wrist.

For a platinum case with a guilloché silver dial, a Mississippi alligator or hornback strap in polished finish — in midnight blue, burgundy, or black colorways — is the most coherent choice for the formal register of the 5317PT. Aged box-grain calf in tobacco or cognac is an excellent alternative for more everyday wear, thanks to the patina that develops over time.

The strap is replaced using a fine-pointed spring bar tool, inserted into the hole of the spring bar positioned inside the lug. Compress the spring bar inward, remove the strap, and insert the new one by snapping the spring bar into position. It is recommended to work on a soft surface to protect the platinum case from scratches, preferably entrusting the task to a watchmaker or the Casati Milano atelier.

Yes. Milano Straps offers a selection of 18 mm straps compatible with the Breguet Classique Complications 5317PT/12/9V6, available in alligator, calf, and other noble materials. For non-standard attachments or particular case shapes, the Casati Milano atelier creates custom bespoke straps, with the option to choose leather and finishes directly at the atelier in Milano.

Durability depends on the material and daily use. A quality alligator strap, with regular maintenance and alternating use, can last 2 to 4 years while maintaining structural and aesthetic integrity. Barenia calf or box-grain, thanks to the compactness of the grain, develops a long-lasting patina but may show signs of wear more quickly on the attachment end at the buckle. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
