Lemania airplane 24 hour clock 1950

This is a clock from an actual airplane. The hands were highly luminescent and it has a distinctive 24 hour display. In it handwind and runs for a couple of days. Still functioning but needs a service when you want it in good running condition. Now it is just very cool. Lemania (from Switzerland) is the brand that also produced the movement for the vintage Omega Speedmaster Moonwatch picked by Nasa for space missions! The clock measures 6cm / 2 1/4 inch in diameter and has a real glass crystal. I guess it is from around 1950.
