I have a used VDO/Kienzel clock for sale, part #901 741 702 02. Google search indicates it is from a '68-'69 911/912. I originally got it from a swap fest intending to put it in an Alfa Berlina I had at the time. That never happened.

Clock runs well and appears to keep accurate time. Please note this clock DOES NOT have a sweep second hand. The white hand can be set at any point on the dial and is a "reminder" dial. The illumination works. I DO NOT have the "U" shaped mounting bracket for it. I am asking $150 for it and will ship at your expense. If you are in SF Bay Area, I am in Sonoma County and you are welcome to take a look at it.
