Reference 5078 was launched in 2005. It is fitted with the ingenious calibre R 27 PS which impresses not only by its remarkable number of 342 parts but also by Patek Philippe's masterly performance of combining a micro-rotor and a minute repeating mechanism in a proportionally small 12 1/2''' movement
The Minute Repeater
On demand, the minute repeater strikes the hours, the quarter hours and then the minutes that have elapsed since the last quarter hour. The first hammer strikes the hours on the low-pitched gong with one strike 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. At 12.59, for instance, the melody consists of 12 low sounds, 3 double high/low sounds, and 14 high sounds – totalling the maximum of 32 strikes.
