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:
