Notes

Produced from about 1990 until 2013, reference 25829 was the king of the line of Royal Oak's featuring a skeletonised perpetual calendar. While the production of these pieces has always been extremely limited, among the precious metals, this stainless steel and platinum is one of the least produced with a total of only 25 watches manufactured. This current examples was purchased new by the consignor and comes complete with its accessories and even comes with an extra tuscan dial that allows the wearer to both have a skeleton and a regular dial.

Provenance

Property of a German Gentleman
