The Most Complicated Watch Ever Made

From Horology magazine, September 1937

The Most Complicated Watch Ever Made

The firm of Patek Philippe & Co. has for years been known as the maker of some of the world's finest watches. It is therefore not surprising to learn that one of the recent creations of this firm is the most complicated watch ever made. This masterpiece is both a repeater and self striking, the hours, quarters and minutes being automatically struck on a four gong chime. In addition it incorporates an alarm mechanism, a split second chronograph and minute and hour register.  Two winding indicators are provided for the two motor mainsprings and a perpetual calendar shows the day of the month, the day of the week, leap year and the phases of the moon.

On the reverse side of the watch are hour, minute and second hands showing 
sidereal time. A small dial contains an indicator for the equation between true time and sidereal time. Two other dials and hands indicate the time of sunrise and sunset while in the center is a celestial chart showing the visible constellations at every hour.

The watch contains some 110 wheels, 50 bridges, +30 screws, 90 springs, 120 miscellaneous parts of mechanism, 70 jewels, 2 dials, 19 hands and 2 discs for the moon and stars. In the construction of this marvelous pi.ece five years were necessary, not counting the preliminary time required for the solution of technical, mathematical and astronomical questions.

We are indebted to Patek Philippe & Co. for the photos and data regarding this unique watch.
