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

The lug width of the Millenary 77247BC.ZZ.1272BC.01 is 20 mm. This measurement is taken with a digital calliper positioned inside the lugs at the base of the case, and it is the key parameter for selecting any compatible replacement strap.

For a white gold case set with diamonds, a belly alligator strap in vegetable-tanned leather is the most coherent choice: its regular grain complements the diamond-set bezel without competing with it. Alternatively, glossy box-calf or shell cordovan offer compact, refined surfaces. A white gold buckle or deployant clasp is recommended for metallic continuity.

To replace the original bracelet with a leather strap, use a fine-tipped spring bar tool or a flat-head watchmaker's screwdriver, carefully releasing the spring bars from the lugs. Given the white gold finish and diamond-set bracelet, it is strongly advisable to entrust this operation to a qualified watchmaker to avoid scratching the polished surfaces.

Yes, any strap with a 20 mm lug width is geometrically compatible with this model. Milanostraps.it offers a curated selection of handcrafted straps in various leathers and finishes, all made to a 20 mm lug width. It is advisable to check the lug curvature profile to ensure a proper fit against the oval case.

The lifespan of a leather strap depends on the quality of the tanning and frequency of use. A vegetable-tanned alligator strap, with proper care — avoiding prolonged water exposure and conditioning every 3 to 4 months — can last between 3 and 5 years while retaining its structural integrity. Casati Milano straps carry an 18-month warranty against manufacturing defects.
