Ref. 25829OR comes up for auction very rarely and will therefore be a very attractive purchase for a collector, who will obtain a charming and very rare complicated mechanical watch from a world-famous traditional watch brand, one of the undoubted leaders in the haute horlogerie watch market. With the recent rush for Royal Oak Perpetual Calendars, this is a perfect chance for collectors to acquire a classic reference that communicates a certain era in the development of the Royal Oak collection – from 1997 to 2014, when the dial of the perpetual calendar had the classic indicator of a leap year, but was still without the central hand of the indicator of the week of the year, which is a customary feature of modern models made on the basis of clones of caliber 2120/2800. The collector’s value of this watch is undoubtedly enhanced by the transparent dial with leaf-shaped hands, which is very rare to the models of the Royal Oak collection, as well as the attractive all-rose gold execution.
