Good luck. It seems like the dreaded cold weather affliction (temps below 50F) cause most small clocks to crap out. However, on a '91 245 that I looked at for a friend recently, there was a digital clock (LCD display) in a round gauge - looked stock. That was a new one on me.

I, too, bought a used small clock on eBay and it suffered the same problem. My fix was an end-around... when the OEM tape player died, I got a new CD player which also has a clock.
