Ahhh, the Audemars Piguet Perpetual Calendar. It’s hard to find a rival to this model (remember the ceramic one last year?), so it should come as no surprise at SIHH this year there are a handful making their debut. The ultra-thin Royal Oak Perpetual Calendar RD#2 might be the splashier release, but there’s also the more established 41mm perpetual calendar being offered in a pink-on-pink combination for the first time. The new addition to the QP collection features the same 41mm case that we know and love, now with a rose gold dial to match. The dial, has dark blue subsidiary dials which make it easier to read the day, date, moonphase, and whether or not it is a leap year (in case you forget). The movement is the same trusty automatic caliber 5134. All-in-all, it’s a solid addition to the collection. Audemars Piguet Perpetual Calendar has been in the business of making Audemars Piguet Perpetual Calendar since the 1950s, and, in fact, AP (along with Patek Philippe) were some of the only guys making perpetual calendar wristwatches at all for the better part of the 20th century. That said, it should be no surprise that they keep introducing new QPs, whether via an entirely new caliber or just by adding a new metal to an existing collection like this one. The current Royal Oak QP was introduced back in 2015, and it has been available in rose gold since the very beginning, but never with a matching dial like you see here.
