I have one of these console clocks, I bought it a long time ago probably on ebay. Because I have a dealer accessory tach on the dash above my steering wheel, obviously I wouldn't have a tach in my dash cluster and no gauges on my console. I really wanted a clock, but I wasn't going to cut up my dash cluster for the center clock.
I had done some research and came to a conclusion that these console clocks were not available for the 69 model year. However recently I saw an auction for a clock with Nov 19th 1968 date code. So now I don't know. I'm guessing if you wanted a clock, this is how a dealer would add it but I didn't find it in the 1969 dealer accessory booklet.
Anyway, I thought the pics would add reference information to this thread if anyone was interested. I will probably add it into my console. Funny how people seem to be interested in the odd accessory stuff during a show, everyone loves talking about the keyhole alarm and chevy dash tach.
