The Junghans Caliber J59 is a well and lean constructed movement with a diameter of ten lignes, which was made probably in the late 1930ies or 1940ies.
It has got a slim and thus vintage looking screw balance, which is not shock protected, a long regulator arm for an easier regulation and in sum fifteen jewels. It’s noteworthy, that those jewels, which are not viewable, since they are on the dial side, are only slight red, almost transparent, while those, which can be seen on the movement plate are dark red. Maybe this was done for cost cutting during the war years.
The plates are slightly decorated with stripes and anglated and the nicely made crown- and ratched wheels achieve a very pleasent look.
On the lean dial side, the Junghans J59 uses a yoke winding mechanism, whose minute work cock is so cleverly constructed, that it hold all wheels perfectly in position, even when the dial is missing.
