http://www.thewatchbox.com The Audemars Piguet Royal Oak Day-Date Moonphase 25594 might be the ideal first complicated Audemars Piguet for a collector of high horology exemplars. Its classical Royal Oak styling features and triple-complication Jaeger-LeCoultre-based movement provide a pedigree that is beyond reproach. Gerald Gentra designed the original 1972 Audemars Piguet Royal Oak to read as a single metal continuity. The bezel flowed seamlessly into the case, the case merged into the bracelet, and the bracelet tapered into a delicate mailed foil below the wrist. This Royal Oak Day-Date exhibits all of those virtues, and it also preserves the exquisitely detailed combination of brushed and polished facets that speak to the quality of the watch under close scrutiny. AP's famous Royal Oak white gold bezel bolts, octagonal bezel, visible bezel gasket, and unique tapisserie dial complete the image of traditional craft quality. That last item expands the roster of Swiss power players that had a hand in this model: Stern Creations (yes, the Patek Philippe Stern family) built every Royal Oak and Royal Oak Offshore "tapisserie" dial until 2012. The final celebrity chef in this haut-de-gamme dish is Jaeger-LeCoultre of Le Sentier. Long famed as the "watchmaker's watchmaker," JLC provided the movement for the very first AP Royal Oak in 1972, and JLC provides a thin automatic base movement for this Audemars Piguet caliber 2224/2825. The complications - a day, date, and moon phase - are alternately practical and romantic. With a movement lineage that includes JLC's awesome engineering heritage, the Royal Oak Day-Date Moon Phase packs serious horsepower in the engine room. Audemars Piguet. Gerald Genta, Stern Creations, Jaeger-LeCoultre. The roster watch industry superstars with a hand in this Royal Oak read like a laundry list of Switzerland's watchmaking greats.
