You are looking at the Patek Philippe Grandmaster Chime Ref. 6300A-010, the most expensive watch in the world. Some lists claim otherwise, but they are wrong, obviously. A simple watch with a zillion diamonds glued to it, does not count. Pocket watches neither, as well as table clocks, church towers and whatever shows the time. Here it is about a highly advanced, analogue, mechanical and technical complicated watch.

This Patek was auctioned by Christies for the 8^th Only Watch auction on the 9^th of November 2019. This auction for a good cause, research on Duchenne Muscular Dystrophy, is biennial and Patek Philippe is contributing a model every event since the start of it in 2005. A unique piece, a one-off, something the buyer will treasure.

The most expensive watch in the world is just from stainless steel

This Patek Philippe has everything collectors want. The huge 47.7-millimeter case is made from stainless steel. Not a real precious material, right? But what counts is what is inside, what it can do and how it is finished. Shall we start?

The Patek Philippe Grandmaster Chime Ref. 6300A-010 has 20 complications which makes it the most complicated wristwatch so far. It has even two new patented features: an alarm that strikes a preprogrammed alarm time and a date repeater that sounds the date when you want. The case with guilloched hobnail pattern is double-faced in order to show all the complications. The dials are golden opaline and ebony-black and there is an inscription “The Only One” on the subsidiary alarm time dial at 12 o’clock. Just to let you know it is very exclusive.

The movement of the Patek Philippe Grandmaster Chime Ref. 6300A-010 took 11 years to develop

The manually wound Patek Philippe caliber 300 GS AL 36-750 QIS FUS IRM needs a crown, six pushers and six push pins to be operated and adjusted. As far as we can see. It has a strike work isolater, a second time zone with day/night indicator and day, date on both dials. Furthermore, there is a month indication, a leap-year cycle by hands, a four-digit year display in an aperture and a 24-hour and minute sub dial. You will also find a crown position indication (R,A,H) and power reserve indicators for the movement and the strike work.

Now you can imagine why it took 11 years to develop this movement. More than 100,000 hours were out into making this watch. The movement is built on different layers and still it is quite compact: 37 millimeters in diameter with a thickness of only 10.7 millimeters. The case itself is 16.07 millimeters. This watch is probably the most advanced and complicated watch ever made. And that comes with a price… Should you want to have one too, but not this one, see if you can buy a gold version.
