PATEK PHILIPPE. AN EXTREMELY RARE PLATINUM CUSHION-SHAPED PERPETUAL CALENDAR SPLIT SECONDS CHRONOGRAPH WRISTWATCH WITH MOON PHASES, DAY/NIGHT AND LEAP YEAR INDICATION

Reference 5951 was launched in 2010 by Patek Philippe and is until today one of Patek Philippe’s leading contemporary examples. Cushion-shaped single-button chronograph watches by Patek Philippe have a long history and go back to the late 1920’s, a time where the Swiss manufacture already produced their technically most ingenious and beautiful masterpieces.

Cushion-shaped examples were rare at the time, and still are today, part of the extremely rare designs found within the Patek Philippe collection. Avid and demanding collectors had an increasing appetite for unique, super-complicated and made-to-measure watches, just like nowadays.

It does not come as a surprise that in 2010, Patek Philippe went back into their prestigious history to inspire themselves in creating this superb split seconds chronograph combined with a perpetual calendar. The single-button chronograph mechanism allows its wearer to operate “stop-watch” functions via the crown, enabling the designers to achieve a most elegant and smooth line. Combining a perpetual calendar with a state-of-the-art chronograph movement, this reference 5951 is one of the most important wristwatches created by Patek Philippe.

Cushion-shaped single-button chronographs with perpetual calendar movements by Patek Philippe are exceedingly rare and are today made in very small numbers.
