Strap for Millenary Précieuse White Gold / MOP

The lug width of the Audemars Piguet Millenary 7227BC.ZZ.A007SU.01 is 20mm. This measurement is taken with a digital calliper positioned internally between the two lugs, not across the outer edges. Any aftermarket strap must match this dimension precisely to ensure correct spring bar insertion and secure attachment to the wrist.

For an 18-carat white gold case set with a diamond pavé bezel, an alligator strap with symmetrical Mississippiensis grain is the most coherent choice: the three-dimensional texture of the leather engages visually with the diamonds on the bezel. Shell cordovan with its smooth, compact finish offers a more restrained elegance that highlights the oval geometry of the case. Both options are available in 20mm lug width on milanostraps.it.

To replace the strap, use a fine-tipped or forked spring bar tool to compress the spring bar laterally within the lug. Given the white gold case and diamond pavé setting, it is strongly advisable to work on a soft surface — ideally a watchmaker's cushion — to prevent scratching the bezel during the procedure. If in doubt, the operation should be entrusted to a qualified watchmaker or to the Casati Milano atelier.

Yes, any strap with a 20mm lug width is technically compatible with this reference. Milanostraps.it offers a curated selection of handcrafted straps in alligator, vegetable-tanned calf leather, and shell cordovan, fitted with steel or precious metal spring bars. Bespoke production through the Casati Milano atelier allows full customisation of material, colour, finish, and clasp — including a white gold deployant clasp to maintain full metallic consistency with the original case.

The lifespan of a leather strap depends on the material and frequency of wear. A high-quality alligator strap, used in rotation and stored away from moisture and heat, will retain its structural and aesthetic integrity for 3 to 5 years. Shell cordovan, owing to the dense fibrous structure of the equine subcutaneous membrane, tends to last even longer while developing a distinguished patina. Straps produced by Casati Milano are covered by an 18-month warranty against manufacturing defects.
