Patek Philippe- Calibre 89

The creation of Patek Philippe Caliber 89 is a historical moment not only for the company but for the world of watches as a whole. This timepiece is the most complicated watch in the world. The watch was designed in 1989 to celebrate the 150 years anniversary of Patek Philippe. Calibre 89 is a 3-pound, 2-sided pocket watch made of gold. Inside a rather small case are fitted 1,728 interacting parts.
Caliber 89 includes 33 complications which represent features that certainly surpassed their time, making the watch more than a simple time displayer. The watch can keep the time of two different time zones as well as display the day of the week, month, year and leap-year, moon phase and even the movement of stars. There are also other interesting features like: time of sunrise and date of Easter. These are just some of the complications.
There were manufactured only 4 models of Caliber 89 and today these models are worth about 6 million dollars each. Truly a remarkable timepiece is Patek Philippe Calibre 89. Although this watch represents much more than a simple Swiss timepiece, the latter is still very difficult to create.
With its 1,728 parts the timepiece weights 1.1 kg and exhibits 24 hands. It took about five years to develop this amazing creation and about four years to manufacture it. Thus today the 18 carat gold most complicated watch in the world displays:
1. Day of the month
2. 12-hour recorder
3. Day of the week
4. Hour of second time-zone
5. Moonphases
6. Winding crown position indicator
7. Century decade and year displays
8. Leap Year Indicator
9. Power Reserve
10. Month
11. Thermometer
12. Date of Easter
13. Time of sunrise
14. Equation of time
15. Star chart
16. Sun hand
17. Time of sunset

Patek Philippe Sky Moon Tourbillon

The rarest complications united in a wristwatch, Patek Philippe unveiled the Star Calibre 2000, one of the most complicated pocket watches of all times.

Barely six months later, the Geneva workshops introduced another Grand Complication - in a wristwatch format.

The "Sky Moon Tourbillon" Ref. 5002 is the first double-faced wristwatch that features a complete presentation of the nocturnal sky on its reverse side.

The masterpiece displays the apparent movements of the stars, the orbit of the moon, the moon phases, as well as the hours and minutes in sidereal time.

As was already the case with the Star Caliber 2000, Patek Philippe's goal in the development of the "Sky Moon Tourbillon" was not so much the number of complications per se. The real objective was to accommodate the most fascinating complications in the small case of a wristwatch: a perpetual calendar with a retrograde date display, a minute repeater, a tourbillon, the display of sidereal time, and a depiction of the nocturnal sky with the motion of the stars, the orbit of the moon, and the moon phases. This turned out to be a formidable challenge because a chart of the heavenly canopy (as seen in the northern or southern hemisphere) requires a certain minimum space to demonstrate the movements of the stars in a sensible and clearly legible manner. The solution adopted by Patek Philippe was borrowed from the astronomical pocket watches made by the company: a moving sky chart on the reverse side of the timepiece. The mechanical module developed by Patek Philippe for the "Star Calibre 2000" was redesigned especially for the "Sky Moon Tourbillon" and was granted Swiss patent CH 688 171 B5.

Patek Philippe’s Platinum World Time

The Platinum World Time created by Patek Philippe was sold at auction for over $4 million USD in 2002. It is believed that only one was created and, at the time, it was the most expensive wristwatch in the world.
In fact, Patek Philippe had produced all of the ten most expensive watches in the world. The company, headquartered in Geneva, made their first wristwatch in 1868. They had already made a name for themselves prior to that, however, by providing watches to Queen Victoria herself in 1851. Other notable customers include Pope Pius IX, a king and queen of Denmark, an Italian king and Saddam Hussein’s son-in-law.

Patek Philippe- The "Graves Complication" Watch

Complication" Watch
The famous Graves Complication - one of the most complicated watches ever made - was completed in 1933. In 1999 it was sold at auction for $11 million, making it the world's most expensive watch at the time.

History
The Graves Complication arose out of an informal competition between Henry Graves Jr and James Ward Packard of Ohio. These two - very rich - men each commissioned a series of ever more impressive watches from the Patek Philippe watch company during the 1920s.

The Graves Complication was the end result of this horological "arms race". It was commissioned in 1930 and completed in 1933. It was a grand complication pocket watch - one which featured more than one complication. In horological terms a "complication" is any extra feature beyond basic timekeeping functions.

This watch was at the time one of the most complicated ever built (it has since been outdone by the Calibre 89 "ultimate" watch). It included numerous complications including split-second chronograph, moon phases and even a chart of the night sky over Graves' home in New York!

Where Is It Now?
When Henry Graves died the Graves Complication went to the Time Museum in Illinois. When the museum closed in 1999 the watch was sold at auction and fetched just over $11 million. It was purchased by an anonymous bidder and has since disappeared from view, probably into a private vault somewhere.

Which is a loss to the world of horology. Hopefully it'll re-emerge one day and return to public display.
