According to todays measurements, the Thiel “Start” caliber is a very raw and large movement, which reminds more of an alarm clock but of a wristwatch. This 12 1⁄2 ligne movement was producted in the version shown here between 1938 and 1950; in modificated versions it was made until the mid sixties.
The brass colored, jewel-less pin lever movement builds very high (approx. 6mm) and consists only of one main plate, which makes any workings on it to a true nightmare, especially when you work on the balance (which shall look a bit a screw balance), which tumbles around in its bearings.
On the dial side, there’s just a rocking bar winding mechanism - a common feature of cheap watches.
The whole construction of this movement reminds me very much of a simple alarm clock, but evertheless, this movement was made and used for many years.
