FAQ

What is the lug width of the Audemars Piguet Millenary 15331OR.OO.D102CR.01?

The Audemars Piguet Millenary 15331OR.OO.D102CR.01 is fitted with an 18mm lug width. This measurement should be taken with a digital caliper between the two lugs at the case, at the narrowest point where the case meets the strap, to ensure a precise fit.

What is the best strap for the Millenary 15331OR.OO.D102CR.01 in rose gold?

For the 18K rose gold case of the Millenary 15331OR.OO.D102CR.01, a mississippiensis alligator strap with polished finish is the most appropriate choice for the watch's character. Cognac, burgundy, and navy blue tones pair more elegantly with the warm rose gold hue compared to black, which would visually cool the overall appearance.

How do you change the strap on the Audemars Piguet Millenary 15331OR.OO.D102CR.01?

The strap is replaced using a flat-tip or lever spring bar tool, inserted into the spring bar housing between the lug and the strap end. On the Millenary, it is advisable to proceed with caution given the curved geometry of the lugs: an incorrect operation could scratch the rose gold. Entrusting the task to a watchmaker or to Casati Milano's atelier ensures a risk-free result.

Are there aftermarket straps compatible with the Millenary 15331OR.OO.D102CR.01?

Yes. All straps with a standard 18mm lug width are compatible with the Millenary 15331OR.OO.D102CR.01, provided that the lug end is shaped to follow the curved profile of the case. Milano Straps offers a selection of 18mm artisanal straps, made to measure by Casati Milano or available ready to ship online.

How long does a leather strap last on an Audemars Piguet Millenary?

The lifespan of a leather strap depends on the quality of the leather, daily care, and conditions of use. A high-quality alligator or calf strap, treated with appropriate products and rotated with a second strap, can maintain aesthetic and structural integrity for 3-5 years or more. Casati Milano straps are crafted with selected leather and guaranteed for 18 months against manufacturing defects.
