Strap for Millenary Hand-wound White Gold / Mother of Pearl

The lug width of the Audemars Piguet Millenary 77247BC.ZZ.A813CR.01 is 20mm. This measurement is taken internally between the two lugs at the base of the case and is compatible with the standard 20mm aftermarket strap range available at milanostraps.it.

For a white gold case with a diamond-set bezel, a glossy black or burgundy alligator strap is the most formally coherent choice. Alternatively, natural shell cordovan or vegetable-tanned calf leather in cool tones (slate grey, midnight blue) enhance the oval case geometry without competing chromatically with the bezel. A white gold deployant clasp completes the pairing in technically sound fashion.

The strap is replaced by removing the two spring bars securing the strap ends to the case lugs. A fine-tipped spring bar tool is required to compress the bar ends without scratching the white gold case. It is advisable to work on a soft surface and, for a first replacement, to consult a watchmaker or follow the guidance of the Casati Milano atelier.

Yes. All 20mm aftermarket straps with straight or slightly curved ends are compatible with the Millenary 77247BC.ZZ.A813CR.01 case. milanostraps.it offers a curated selection of 20mm handcrafted straps produced by Casati Milano in alligator leather, shell cordovan and vegetable-tanned calf, with customisable finishes and stitching.

The lifespan of a leather strap depends on the material, frequency of use and maintenance routine. A quality alligator strap, rotated regularly and kept away from prolonged moisture and perspiration, maintains its structural integrity and appearance for 3 to 5 years. Shell cordovan, owing to the density of its fibres, tends to last longer and develops a distinctive patina over time. Casati Milano straps carry an 18-month warranty against manufacturing defects.
