Forget the $17,000 gold Apple Watch - this $2.5 million Patek Philippe is the most complicated wristwatch in history
Of course, that's small potatoes compared to this $2.5 million Swiss watch which is arguably the most complex wristwatch that has ever been made.
For its 175th anniversary, the luxury Swiss watchmaker Patek Philippe invented a collection of limited-edition commemorative timepieces called The Grandmaster Chime with 20 complications, two dials, and 214 parts.
The watch measures 47.7 mm in diameter and has 1,366 individual components. It took a whopping eight years and 100,000 man hours to develop, 60,000 of which were spent just on the watch's movement.
Patek Philippe calls the Grandmaster Chime an "intelligent watch" with features such as a minute repeater, instantaneous perpetual calendar with a four-digit year display, and a second time zone.
It also has two deluxe features that are a world-first for chime watches, including an acoustic alarm that strikes the alarm time and even a function that chimes the date.
Both sides are equally stunning. The 18k rose gold 16.1 mm thick clasp was fully engraved by hand. Even the strap is meticulously designed - hand-stitched and made from alligator.
And for those who want to purchase the remaining six, it's not enough to have $2.5 million in the bank. Lucky customers must also be interviewed by Thierry Stern, the chairman of the watchmaking brand.
"I would like to chat with the client and make sure he's a watch lover and make sure he's going to enjoy the watch for many years," Stern told CNBC.
