My one week trial period is complete. These two 70's digital clocks were started at the same time and sync'ed to my computer. The test was done to find the variation in accuracy between these 2 electric veterans. The week ended and there was a 3- 3.5 second difference between them.
The newly crowned winner of the most accurate time piece (compared to my internet connected computer) is.....

The square cased,gold coloured clock - with no obvious variation from the aformentioned computer's time.
Have a great weekend one and all, hope to see plenty of family photo's posted.
