This watch was a real coincidence hit. Fortunately, a photo of the movement was also shown at the time of sale without that the watch would never have been identifiable as a Junghans watch - the movement was a Junghans J54. The original version came from the Schwenninger branch of Junghans and was still marked with the butterfly or completely without. It was not until the closure of the Schwenningen company (20.06.1931) that the small watch production was completely relocated to Schramberg, but earlier Schwenningen had already reduced their production.
It can therefore be assumed that the movements without a butterfly but with the embossed caliber number 54 were made around 1931 or even earlier. Probably a short time parallel movements from Schwenningen and Schramberg were sold and Junghans used the "cheap brand" with the butterfly also parallel to the more expensive watches that were marked with the Junghans star.
The above watch with caliber 12''' shows the Schwenninger butterfly on the dial and on the board.
The above watch with the caliber 12''' shows no mark (collection B. Schmotte).
The watches made in the Schwenninger company have no nickel-plated surface, the caliber J54 produced in Schramberg already had. The Schramberg boards of most watches have a stepped, outer polished area and an inner area with a strip finish. As a rule, the Junghans-star has also entered the dial here and the number of the caliber (54) is stamped on the movement.
The caliber Junghans J54 has a pin lever escapement and so far two versions are known - both with a small second
The watch now found has many surprises. The dial is the first enameled dial that I have ever found on a Junghans wrist watch.
On the hands meanwhile are only remnants of luminescent visible and on the dial is no more luminescent mass. Here I can only assume that on the enamel luminous dots should have been applied.
The screws holding the dial have already peeled off the enamel and it has been glued provisionally around both screws to secure the enamel.
There is the simpler version of the Junghans J54 with pivot balance and without jewel bearings and the better equipped variant Junghans J54a with pin balance and seven jewels.
With the now discovered watch, a lot is different: no small second. The watch has no pivot balance, but a balance pin, but no jewel bearings were installed. The one end was unfortunately broken, but in the fund is already a suitable spare part ready.
This watch is for me a real surprise - no balance with pivot staff, in spite of the pin balnce no jewels, but metal bearings, no small second and then also an enamel dial! Junghans always amazes me ...
