My friend gave me a clock to repair. We guessed maybe 1950s aesthetic - very mid-century modern.
Digging through the Junghans archives, I found a similar clock in a 1954 catalog - and then tracked it year-by-year to find the 1964 version I have here.
How it started [1954]: 20/6065
How it's going [1964]: 20/6171"8 day strike on membrane-gong “Bim Bam". 3 rods"
