The newest version of the Audemars Piguet Royal Oak Perpetual Calendar goes for what many would consider old-school horological luxury with its classical yellow gold case. The watch is powered by in-house Caliber 2120 and boasts a deep blue Grande Tapisserie-patterned dial. The calendar displays are on prominent subdials at 9 o’clock (day), 12 o’clock (month and leap-year), and 3 o’clock (date). In addition, an astronomical moon-phase display appears at 6 o’clock and the week of the year is indicated on a numbered 1-52 chapter ring surrounding the dial.
