How to Identify a Kern & Sohne Clock

Kern & Sohne Clock Company was formed in 1937 by Karl Kern and his sons. The company produced mainspring-driven 400-day "anniversary clocks" up to 1985. The 400-day clocks manufactured by various companies have similarities which, at first impression, can be difficult to identify if the brand is not noted on the dial. Since 400-day clocks are shielded with a clear glass dome, identifying the Kern & Sohne clock requires no special skills or tools.

Check the dial. This is the most expedient method of identifying a Kern & Sohne clock. On some clocks, only the name "Kern" may be present on the dial.

Check the back plate of the clock for further verification.

Examine the lower right-hand side of the back plate for the name "Kern & Sohne" engraved into the brass.

Look at the lower left side of the back plate for a conspicuous circle with the letters "KS" within it. Immediately below the circle, check for the word "Germany."
