The Watch
In 1956 Jaeger-LeCoultre launched the K815 caliber, the world's first automatic alarm wristwatch, the Memovox Automatic. The automatic winding of this watch had a pendulum (even called: bumper), which rotated in an angle of about 110 °, It was limited by two springs and stored the energy in the barrel for the time function.
In 1959, the Memovox Automatic, reference E855 received a date display with the automatic caliber K825. This calibre consisted of 241 individual parts and was built in a quantity of about 45,000. The K825 was used in the models of the E855, the E859 (also referred to as Polaris, in two versions of 1965 and 1968), and the E861.
The first form of the indices of the European E855 came with attached Arabic numerals "12" instead of the "JL" logo on later models. The last two forms of the indices came with an attached triangle on the central alarm disc of the clock to indicate the alarm, while in the earlier models the triangle was painted on the alarm indication disc. The first two forms of the indices were offered with watch hands in dauphine form, the last three, however, with bâton hands.

The Condition
This watch is a true stunner! It really is something with black dial on a Memovox!
The dial is 100% original with small signs of patina. As you can see the dial have developed a stardust-effect. At the left side of the dial there are small dots on the dial but as you see, they are more or less visible depending of how the light hits the dial. The lume dots are intact and have developed a brown-ish colour.
The triangualar on the sliding alarm disc is painted. The case is well preserved but got some small signs of wear. The crystal is like new. The crowns are JLC-signed (which is uncommon, these are most often re-placed). One crown is re-placed but with a JLC-crown and fits very good.
The vintage J.B Champion flexi is in nice condition and the Hirsch strap is new.
