I'm not a wrist watch person, I stopped using when I bought my first cell phone, a long time ago. But the microscopic precision and detail on one of these are absolutely ridiculous. They're not exactly the type of people that are into the makers movement, but these guys sure got skills!

The Grandmaster Chime was made to celebrate Patek's 175th anniversary, it's double faced with time on one side, and date on the other. And it cost merely $2.5 million. A bargain.

The parts that compose the watch are so small that they have to build it using magnifiers, microscopes and tweezers. Probably like any other watch, but by the size of this one and the amount of parts it might be one of the most complex there is.


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.
