The reference 5951 was presented to the market at the Baselworld Fair in 2010. The watch features a black dial with a silver subsidiary dial and red chronograph hands, which give the watch a very charming and contemporary look that greatly enhances its fascination for collectors.
The watch is powered by the CHR 27-525 PS caliber, which is the thinnest broken chronograph movement with column wheel ever created by Patek Philippe. It allows the wearer to use the split chronograph with the crown and gives the watch a fresh, modern but elegant appearance.
The perpetual calendar with moon phases composed of only 148 pieces is housed in a space of just 27 mm. in diameter by 2.05 mm. thick. In addition to the lunar cycle, the mechanism animates a hand-held calendar as well as window indications of the day, the month, the day / night alternation and the leap year cycle. Among its particularities is a continuous 60-minute counter led by the gear pinion passing through small parts, an ingenious construction that contributes decisively to the ultra-flat profile of the movement.
The design of the cushion-shaped 37 mm case, the single button single-button chronograph movements for split seconds by Patek Philippe are extremely limited and extremely rare.
Complete with all the accessories, this very refined wristwatch combines the most sought after watchmaking complications and is increasingly popular with collectors.
