Alarm Clock

Q: A relative left me a Swiss-made clock called a “Twin Dial Alarm Clock.” It has a clock face on both sides and still runs. The box it’s in says the maker is Semca. Please tell me something about it and what it’s worth.

A: Semca Clock Co. was based in Germany, but it had an office in New York City. It made a lot of styles of clocks and wristwatches, including a few double-face clocks like yours. Your alarm clock dates from the middle decades of the 20th century and was designed to sit on a shared nightstand between two single beds. Another, larger double-face model was made to sit on a partners desk. We have seen your clock sell online for $25 to $50.
