As You know I have a special fable for electro-mechanic clocks of the early post-WW II aera.On the first visit to a regional flea market this year I saw these three beauties,they cost me 2€ each and some hours of "work".
From left to right:signed Mauthe electric,containing a Junghans electrical motor remontoir,switching on and of every 2-3 minutes to wind a small standard mainspring powering a nice 7jewel pin pallet esc. balance movement.
in the middle:Emes kickwind mvmt,7jewels,pin pallet escapement,a long spiral mainspring like in a ball-pen spreading through the whole movement;
the right signed Blessing electric containing a Staiger Chrometron movement with a large balance wheel beating half seconds and an "escapement" with an electromechanic pivoted detent.Like in a chronometer the balance recieves impulse only once in a second while swinging in one direction,the backswing is allmost free when a "gold spring" let pass the impulse piece without resistance.This movement acutally was the precursopr of the first "affordable" quarz movement of German production.The balance wheel was replaced by a quarz crystal and a set of frequency dividers at the end giving impulse once per second the the electro-mechanic element wich advances a ratchet wheel once per second.It's all in plastic since Staiger originaly was a producer of plastic articles.
All in all a nice prey promising a good prosperous year!
