Two months ago on October 12th, 2014, Patek Philippe presented 25 timepieces to celebrate its 175th anniversary as reported here. One of these 25 commemorative timepieces is the Patek Philippe ref. 5975, a Multi-Scale Chronograph available in three precious metal variations and with a dial fitted with a tachymeter, telemeter and a pulsometer. With these chronographs Patek Philippe has returned to the source of the chronograph by creating a multiple-scale instrument whose face combines technical panache with finesse. Patek Philippe has always accorded a prominent role to the chronograph. Between 2005 and 2012, reaffirmed its know-how and supremacy by developing a range of eight chronograph movements built entirely in its own workshops. They extend from the classic manually wound chronograph with column wheel and horizontal clutch to the self-winding chronograph with vertical disc clutch and to the highly complex split-seconds chronograph, with or without perpetual calendar.

To pay tribute to its 175th anniversary, Patek Philippe created a collection of 25 limited-edition commemorative timepieces that include the Grandmaster Chime ref. 5175R, the Chiming Jump Hour ref. 5275P, the World Time Moon ref. 5575 and ref. 7175, six Multi-Scale Chronographs under ref. 5975 and ref. 4675, three different sets of four Calatrava watches —a set with cloissoné enamel dials, a set with hand-engraved dials and a set with wood marquetry dials— ref. 5089 featuring motifs of the Lake Geneva Barques and lastly three different pocket watches. One of the celebratory pieces that stands out from the rest is the Grandmaster Chime ref. 5175R which is so far the most complicated wristwatch of the eminent family-owned watchmaking companies and decidedly one of the world's most elaborate wristwatches. This is due not only to the number of complications involved but also to the horological degrees of complexity, two of which have been added to the annals of watchmaking for the first time.
