Patek Philippe Grand Complications 5470P-001 1/10th Second Monopusher Chronograph Blue Dial 41mm Platinum Navy Blue Leather Straps Men’s Watch
The Patek Philippe Grand Complications 5470P-001 1/10th Second Monopusher Chronograph is Patek Philippe’s first high frequency movement (5Hz, compared to the usual 4Hz), its first 1/10th seconds movement, and a new way to display 1/10ths of a second on a dial.
Patek Philippe holds no less than 31 patents on the movement, seven of which are applied specifically to this reference. Essentially, its technical feat is the display of 1/10th of a second on the central dial simultaneously with the central chronograph seconds hand.
The movement, CH 29-535 PS 1/10, was 10 years in development. It is based on Patek’s split seconds chronograph movement, which has been around since 2009, but the rattrapante function has been replaced by the 1/10th seconds function. That sounds simple, but it was anything but.
