Made for the 175th anniversary of Patek Philippe in 2014 and in 175 examples, this watch is both subtle and outstanding at the same time.
First, there a striking mechanism which chimes on the hour. Such a complication was last seen in a wristwatch in 1920. The function can be turned on or off with the slider on the left hand side.
Second, the movement (manual winding 32-650 HGS PS) was engineered so that indicators would jump so rapidly that they seem to be instantaneous. The seconds hand jumps in one second increments and the hour disk doesn’t slowly transition to the next numeral due to a mechanism which jumps and perfectly centers the numeral so quickly that it seems instantaneous; for example, the disk will still be centered on 11 at 11:59:59 and then on the next second the numeral 12 will appear and the disk will be centered on the numeral 12 at 12:00:00. In time setting mode, the seconds hand is stopped (joy) and there is a minute detent system where the rotation of the crown is converted into clicks which jumps the minute hand to be centered on the minute marker, no incorrectly aligned minutes hand with respect to the seconds (joy of joys). All of this is pure poetry in motion.
My only major criticism is that of the missing minute markers for 58 to 3 inclusive. The same arc for the minute markers for 27 to 33 inclusive should have been employed.
My pictures don't do this watch justice but it is an exceptional watch and one that has left a lasting impression on me.
