Patek Philippe Grandmaster Chime: Building process of the world's most complicated watch
Patek Philippe just released the "most complicated wristwatch of the eminent family-owned watchmaking companies and decidedly one of the world's most elaborate wristwatches." for their 175th anniversary.
Patek Philippe's Grandmaster Chime is a wrist-format timekeeping instrument of absolutely unprecedented complexity and ingenuity that establishes new benchmarks in terms of technical and aesthetic elegance. Its double-face case with a diameter of 47 mm, it accommodates four spring barrels and no fewer than 20 complications, including coveted functions such as a Grande and Petite Sonnerie, a minute repeater, an instantaneous perpetual calendar with a four-digit year display, a second time zone, and two patented global debuts in the domain of chiming watches: an acoustic alarm that strikes the alarm time and a date repeater that sounds the date on demand.
The $2.5 million watch's movement has 1,366 parts and the 18K rose gold case is hand graved. Watching the pieces fits together is strangely satisfying.
