The ETA caliber 955.414 is a 3-hander quartz watch movement with a date. This 7 jewels movement is parts of ETA’s Normflatline Standard family of quartz calibers. Based on technical documents, this caliber has been around since at least February 24, 1987. While this movement was presumably produced in Switzerland, none of the examples found online appear to be signed Swiss or Swiss Made. If you have an example with country of origin (on the movement, not the watch dial or caseback), please share below.
