Strap for Millenary Hand-wound White Gold / Diamond

The lug width of the Millenary 77248BC.ZZ.A111CR.01 is 20 mm. This measurement should be taken with a digital calliper positioned between the lugs at their narrowest point, excluding any lateral protrusions of the white gold case.

Given the haute joaillerie nature of this reference — white gold set with brilliant-cut diamonds — the most coherent choice is a belly alligator strap in vegetable-tanned leather or a shell cordovan strap. Both materials offer a natural grain texture that contrasts elegantly with the geometry of the diamonds. A white gold deployant clasp completes the pairing with material consistency.

The strap is removed using a fine-tipped spring bar tool, inserted into the lug slot and compressing the spring bar inward. Given the white gold case set with diamonds, it is strongly advised to work on a soft surface and to protect the lugs with non-abrasive tape to avoid scratching the stones or the metal. When in doubt, consult a qualified watchmaker.

Yes. Any strap with a lug width of 20 mm is technically compatible. milanostraps.it offers a curated selection of handcrafted straps in alligator, box-calf and shell cordovan leather, available ready-to-ship or made to order. All are compatible with the 20 mm lug of the Millenary. Material, stitching and closure can be fully customised through the Casati Milano bespoke service.

The lifespan of a leather strap depends on the material, frequency of wear and care. A high-quality vegetable-tanned alligator strap, worn in rotation and kept away from prolonged moisture exposure, typically maintains its structural and aesthetic integrity for 2 to 4 years. Shell cordovan, owing to its dense fibre structure, tends to last longer and develops a distinctive patina over time. Casati Milano straps carry an 18-month warranty against manufacturing defects.
