Patek Philippe buries the lead , launching a highfrequency chronograph just after Geneva show .
LEADING WITH A NEWLY DESIGNED TRAVEL TIME WATCH that now includes an annual calendar , Patek Philippe at Watches and Wonders 2022 debuted twelve new watches , including three models designed with a feminine focus .
Perhaps to give the new Annual Calendar Travel Time its own spotlight , Patek Philippe waited until just after the Geneva show to launch a splashier technical innovation : the new 41mm platinum-cased Patek Philippe Ref . 5470P-001 , a 1 / 10-of-a-second monopusher chronograph .
To engineer its first high-frequency chronograph Patek Philippe started with its existing CH 29- 535 PS caliber from 2009 . Watchmakers amped the frequency from 4 Hz to 5 Hz ( 36,000 vibrations per hour , or ten steps per second ) and then equipped the movement with an additional 1 / 10th of a second chronograph mechanism .
As Patek Philippe explains , the designers provided the caliber CH 29-535 PS 1 / 10 with two independent and synchronized chronograph mechanisms , each of them driving a different central hand . The hand that performs a complete revolution per minute shows the stopped seconds in the traditional manner . The other hand ( in red lacquered Silinvar ) performs one revolution per twelve seconds .
