IKEA really does have a cheap wind-up alarm clock. There's a video.
At $6, that's a reasonable way to get a wind-up mechanism. You can also buy "wind up motors" (the correct term is "spring motor").
Here's a video on phonograph spring motor repair
, for a rather nice governed Victrola spring motor. There are also wind-up motors in the Lego family.
I want this backwards clock!
At a local auction one time, amazed at how high the bidding was going for an imitation Chronometer.
I finally said, "But it says Quartz on the dial!"
Bidders paused, looked at me for a moment, then continued to bid it up to around $200.00 !
They had no clue what I was talking about, but they had all looked up "Chronometer" on ebay with their cell phones. I just had to sit back and smile. They thought they were being smart by looking it up, but in reality had no clue about the difference between a real Chronometer and a quartz clock movement.
At the auction, I'm known as the guy who likes the old radios and the old alarm clocks. The rest of the lot bid like crazy for "Quartz" coo-coo clocks and "Quartz" anniversary clocks. I know many of the 1940's and 1950's wind up alarm clocks have brass mechanisms in them.
They think I'm crazy, and I think they are crazy. I get real brass mechanisms for 50 cents and they pay hundreds of dollars for plastic Quartz mechanisms made in China a couple of years ago.
I like our relationship!
