Authentic legendary collector's watch  1950s  All original.  Crocodile skin strap  New, never worn  In its original box  Dial 35 mm It is the first battery-powered Lip and Europe's first battery-powered wristwatch. Its defining characteristic is its two-battery electro-mechanical movement, which gives it a lengthened shape. It was produced from 1958 to 1963. This type of movement was revolutionary for watchmaking. Put simply, electronic or electro-mechanical watches have nothing to do with quartz watches. They are closely related to mechanical wristwatches and do in fact tick. In simple terms, the balance wheel contains a permanent magnet which is attracted by a coil. When it reaches a predetermined angle, contact is made with a wire under the balance wheel which reverses the current in the coil. The magnet is thus repelled and the cycle resumes. This wristwatch is difficult to find as it was not produced for very long. R27 movement.   First electronic wristwatch.
