Prisma Art Deco 935 silver cabriolet purse watch travel clock features a transforming mechanical shutter case in silver with black hot enamel geometric panels. The original silvered dial is signed Prisma and showcases stylized Arabic numerals, luminescent tracking, and original hands for a crisp 1920s–1930s look. Crafted in high-grade continental 935 silver and stamped CFB inside the case for Carl Friedrich Bosch/Charles Frederik Bosch, it references US Patent #1651804 (Dec 6, 1927) for the travel clock case mechanism and bears case serial number 62174. This compact antique timepiece is ideal for a collector’s display in an office, bedroom nightstand vignette, or entryway catchall tray, and it also makes a distinctive gift for an Art Deco design lover.
