Minute Repeaters. A repeater is a complication in a mechanical watch that audibly chimes the hours and minutes at the press of a button. This complication originated to allow the time to be determined in the dark, and were also used by the visually impaired. The minute repeater chimes the time down to the minute, using separate tones for hours, quarter hours, and minutes, usually with low tones for the hours, a sequence of two tones for the quarter hour and high tones for minutes.For example if the time was 3:17 p.m. that watch chime would be as follows: bong - bong - bong (3 hours) - bing-bong (15 minutes) - bing - bing (2 minutes). If you want to hear what a minute repeater chime sounds like you can visit Robert Maron's Minute Repeater Sounds Archive (use Internet Explorer as it does not seem to load properly with Mozilla).
Patek Philippe Ref. 3939 Grand Complication. The Patek Philippe 3934 is a manually would minute repeater wristwatch with a 36mm case diameter. A lever on the left side of the watch activates the minute repeater function. The watch is available in white gold, yellow gold, rose gold or platinum. It is powered by a Patek Philippe lever tourbillon movement.
What is a tourbillon? The tourbillon was invented in 1795 by Abraham-Louis Breguet. Mechanical timepieces are affected by gravity. In order to counter the effects of gravity, Abraham-Louis Breguet built a watch that counteracted gravity by rotating the balance wheel of a watch or clock through 360 degrees. This is called a tourbillon.
This is accomplished by mounting the escapement in a rotating frame, called a "carriage" which turns at regular intervals, usually once a minute. This rotation reduces the positional errors of the movement.
At that time almost Abraham-Louis Breguet invented the tourbillon almost all watches were pocket watches which stayed in one position most of the time. The only time a pocket watch changes position is when it's taken out by the owner to check the time.
The effect of gravity on a watch or clock kept in one position all the time, like a pocket watch, is particularly noticeable on the escapement, especially the balance which rocks back and forth. This can lead to inaccuracies. Breuget's solution was the tourbillon.
Today, most tourbillons are found in wristwatches. People tend to move their arm as they go about their day, which provides the changes in position required to offset the effects of gravity on the watch movement. This negates the need for one a tourbillon. Today tourbillon watches are valued as a display of watchmaking prowess, in the same way complication watches are desirable.
Paying homage to Breguet. Interestingly the first repeater wrist was created by Breguet in 1789. Breguet did not invent the repeating mechanism, which in itself is not all that complicated, but was the first to be able to put it in a pocket watch was a great challenge.
Interestingly enough, the Patek Philippe 3839 grand complication includes two of Breguets greatest contributions to watchmaking.
About Patek Philippe. Patek Philippe & Co. was founded in Switzerland in 1851. The companies emblem, the Calatrava Cross, was adopted by it at the end of the 19th Century. It is acknowledged as one of the finest, if not the finest, watchmaker in the world.
