Summary
|
This is a very rare and exceptional example of Jaeger LeCoultre’s (JLC’s) first automatic winding watch, Calibre 476 also known as the 12A. This vintage watch was introduced in 1946 and represented significant effort by JLC designers and watchmakers. The watch is in extraordinary condition. We were fortunate to obtain it from the family of the original owner. Early automatic watches used something called a bumper wind, which involves two springs that push a weight back/forth as you move your hand. Later automatic watch movements used a spinning rotor that spun when you moved your hand. Bumper wind automatics are very efficient and reliable movements and are fun to wear as you can feel the automatic weight move back-and-forth with each wind. As one of Switzerland’s finest watchmakers with a long history they are proud of, JLC featured this specific watch model including the same dial, case, and hands on their website several years ago. We purchased this watch from the family of the original owner. This watch in extraordinary condition. With its beautifully aged mellow dial, blued hands, and pristine case, this watch is a rare find and looks simply fantastic on the wrist.

ClockSavant Watchmaker Testing, Certification, and Performance Measurement
All the watches we sell go through a comprehensive series of ClockSavant-developed functional, stability, and performance tests and are only approved for sale if they meet or exceed the criteria we have established. Performance measurements for this watch are provided below. See the Support page of our website for an explanation of watch performance measurements and guidance on interpretation. The watch performance values provided do not necessarily reflect the accuracy you will experience based on your unique watch wearing habits. You may experience a gain or loss by as much as approximately 1 minute per day with vintage watches.
Legend: Rate, Amplitude (Amp), and Beat Error (BE) are provided for Dial-Up (CH) and Dial-Down (FH) positions. Averages (Avg) are also provided. These represent the average performance of the watch across all 6 traditionally measured watch positions which, in addition to dial-up and dial-down, are the vertical positions of Crown-Up, Crown-Down, Crown-Left, and Crown-Right. Rate is expressed in seconds gained or lost during a 24 hour period. Amplitude is in degrees. Beat Error is in milliseconds. Lift Angle used in measurement is unique to the particular watch calibre.
