The self-winding movement with a strike train embodies all functions of a full calendar as well as a moon-phase display. The Ref. 5074 stands out with remarkable sonority. Patek Philippe devoted considerable resources to metallurgical and acoustic research with the aim of crafting gongs that produce an incomparably pure sound. On demand, the minute repeater strikes the hours, the quarter-hours, and the minutes that have elapsed since the last quarter-hour. One hammer strikes the hours on the low-pitched gong once for each hour. Subsequently, each quarter-hour is sounded as an alternating double strike by two hammers on both the high- and low-pitched gongs. Finally, the second hammer strikes the high-pitched gong to count the number of minutes that have passed since the last quarter-hour. 12 low strikes, three double high-low strikes, 14 high strikes: This constitutes the melody with a total of 32 strikes at 12:59. The “cathedral” Gongs To optimize the acoustic quality of a minute-repeater wristwatch, the “cathedral” gongs are shaped to encircle the movement not just once, but nearly twice. This makes them almost twice as long as conventional gongs. The
