I’ve tested it several times, and it works flawlessly.
Vintage Umbra Mechanical Wind-Up Alarm Clock Green Dial Chrome Case Twist Works
Product Details
An early Umbra mechanical wind-up alarm clock from the brand's first years, dating to circa late 1970s–early 1980s, before quartz and batteries took over. This clock runs on a true mechanical movement — you wind it by hand, no batteries, no electronics, just gears and craftsmanship. The bold green dial, raised numerals, and reflective chrome case give it that unmistakable retro-modern look that works just as well in a minimalist space as it does in a vintage- interior. It feels solid, purposeful, and intentional — not decorative fluff. Early Umbra pieces like this are getting harder to find, especially in mechanical form. Most clocks you see now are quartz; this one is from the short window when Umbra was still producing wind-up alarms, making it a standout for collectors, designers, and anyone who appreciates objects that do something real. Perfect for: • Nightstand or desk styling • Retro / mid-century interiors • Collectors of early Umbra design • Anyone tired of disposable, battery-dependent clocks Details • Brand: Umbra • Circa late 1970s–early 1980s (early Umbra era) • Mechanical wind-up movement • Alarm function • No batteries required • Green dial with raised numerals • Chrome-tone metal case • Made in China Condition Vintage condition with visible wear to the chrome consistent with age and use.
