‘The Owl’ 25572ST Audemars Piguet Royal Oak Day Date

Not all Day Dates come in Oyster cases. Shortly after the 5402 graced the world with its presence, AP experimented with a few variations on the theme. Out of this early/mid 80s era came many of the iconic complicated Royal Oak offerings we revere today. However, the very first complicated offering to feature in AP’s midsized 36mm case was this ref. 25572. Unlike the jumbo case which debuted the perpetual calendar and chronograph offerings, the midsized approach was more discreet. This 25572 debuted AP’s approach to a sporting Day-Date, one which featured two clean and minimal registers. Many have not seen or heard of this reference in 36mm, as it was produced for only a few years and discontinued. Today, it more commonly goes by ‘The Owl’.


This reference represents the latter productions characteristically, with a mixed-height Audemars Piguet signature, unsigned crown, and lumed Tapisserie. The dial was executed in a white tone, which has become increasingly cream in age. The two oversized calendar counters which gave this reference its name have a tendency to oxidize over time and that process is only just beginning on this example. Interestingly, both lumed and non-lumed hands have been observed in this reference with no correlation to time of production. This may be a servicing artifact not well documented, however.


A huge part of the charm of this reference are in equal parts the lack of hype and extreme specificity. Everyone will know and recognize the Rolex Day-Date approach. Even many seasoned AP people will not be certain just what this dial is doing in a 36mm case. Moreover, there is the degree of practicality added by the automatic calibre 2224/2825 (JLC derived) with rapid-advance setting and usefulness of the Day-Date itself. It is worth noting that the fully integrated steel case tends to wear a bit more like a 37 or 38, as most Royal Oaks view larger than measurements suggest. Overall production numbers are not known, but great examples such as this are not an easy hunt.


This example is great. The case is very full but has a slight factory polish. Its dial is full cream in tone, as is the tritium. The watch comes with a full set, extract, and service papers. Someone really loved this example. It comes from a well-regarded dutch retailer.
