First introduced in 2008, the Grand Complication Ref. 5207G (price on request) is the only watch in the current Patek Philippe collection that features a minute repeater, a tourbillon, and a perpetual calendar. This year, the reference was updated in a rich shade of blue that enhances the watch’s complications. The other three models released in 2008, 2012, and 2015 are no longer available, but if you have your eye on this beauty, get in line. This is the crème de la crème of Patek Philippe watchmaking, and this highly complicated grande sonnerie comes with a six-figure price tag and an application process—typically limited to Patek Philippe collectors.
