This is a wonderful, vintage, free form crystal clock made by Schneider Glass Company in France. The clock face is removable and currently, is not in working order, but uses a mechanical movement which must be wound. The clock is made by Europa and is similar to a standard vintage travel clock which winds and has glow-in-the-dark markers on the dial.
Measures 5" x 5" x 4"H. Date of piece is unknown, but judging from the style of the Europa clock, we would venture to guess ca. 1960s. See images for details. This piece is signed. The condition is fair, considering there are some chips in the bottom and the clock is not currently working.
