Strap for Millenary Hand-wound Frosted White Gold / Aventurine / Bracelet

The lug width of the Millenary 77244BC.GG.1272BC.01 is 20mm, measured between the case lugs at the strap attachment point. It is advisable to confirm this measurement with a digital calliper before purchasing an aftermarket strap.

For this white gold model featuring a diamond pavé bracelet, a vegetable-tanned alligator strap in midnight blue or polished black is the most coherent choice for its formal register. Shell cordovan in burgundy is an equally refined alternative, developing a distinctive patina over time. Both are available in 20mm on milanostraps.it.

Strap replacement is carried out via the standard spring bars fitted within the case lugs. Using a dedicated spring bar tool or fork-style tool, compress the spring bar, slide out the original strap and fit the new one. Note the slight downward curve of the lugs: prefer pre-bent strap ends or leather with a heel thickness not exceeding 4mm.

Yes. Any 20mm strap fitted with standard 1.8mm spring bars is technically compatible. Milanostraps.it offers a curated selection of handcrafted 20mm straps in various materials — alligator, calf leather, shell cordovan, rubber — available bespoke or ready to ship, with either a pin buckle or deployant clasp.

Longevity depends on the material and frequency of wear. A quality vegetable-tanned alligator strap can last three to five years with regular use, developing a personal patina over time. Shell cordovan tends to last even longer owing to its dense fibre structure. Exposure to moisture, perspiration and fragrances accelerates wear: it is advisable to rotate between at least two straps and to condition the leather periodically.
