Vintage General Electric flip digit alarm clock, 1970s made in Singapore. We've tested this and it works fine.
BUT the alarm isn't as loud as many of today's clocks, and the back light behind the numbers is not as bright as a modern clock is, either. That's part of the charm, I think. Though I thought I'd mention it, since today's gadgets are much easier to see and hear!
Measures 7 1/2" long x 3" tall. Case and cord are clean, without a lot of scratching.
