Patek Philippe Minute Repeater Perpetual Calendar Ref. 5074P-001 The Patek Philippe ref. 5074P-001 joins two of the house's grand complications, a minute repeater and a perpetual calendar, in a 42 mm platinum case. Calibre R 27 Q chimes the hours, quarter-hours and minutes on demand on Patek Philippe's "cathedral" gongs, which wrap almost twice around the movement for a longer, richer sound. The black dial carries applied Breguet numerals: day and 24-hour indication at 9 o'clock, month and leap-year cycle at 3 o'clock, date around the moon phase at 6 o'clock. - Self-winding Calibre R 27 Q with minute repeater, perpetual calendar and moon phase - Cathedral gongs, sounded by a slide on the case flank - Not water resistant, so it is kept away from water, as a minute repeater should be Frequently asked How does the minute repeater strike the time? One hammer sounds the hours on the low gong, the quarter-hours sound as high-low double strikes, and the minutes since the last quarter-hour sound on the high gong: 32 strikes at 12:59. When does the perpetual calendar next need correcting? Worn regularly or kept on a winder, not before 28 February 2100. This example shows light marks on the platinum bezel and case, consistent with its condition. Maker: Patek Philippe. Reference: 5074P-001.
