Patek Philippe definitely made its 175th anniversary memorable by introducing The Patek Philippe Grandmaster Chime Ref. 5175 wristwatch. Excellence in quality, design and materials makes this masterpiece nearly a definition of a timepiece. In addition, it is the first double-face wristwatch presented by Patek Philippe. Not only does it contain four spring barrels powering 20 complications including Grande and Petite Sonnerie, but also a minute repeater, a calendar with four-digit year display and a second time zone, an acoustic alarm that strikes at the alarm time, and a date repeater that sounds the date on demand.
Currently its retail price is conceived to be 2 million pounds, but we can really notice the amount of effort and new technologies that made this watch become a reality.
