I bought a T3 clock from a show over a year ago and it worked. For £10 l was as happy as a pig in the mud. The joy of time travel didn't last long and within a few months it came to a stop. Having taken it apart l thought l had discovered that it had a dodgy earth so set about making a new one and all was good again. It was good for about a week and then it died again. Fed up with the whole thing l decided to rip out the Volkswagen mechanicals and go battery with one of those quartz clock mechanicals. The change over was easy. l had bought 3 types with different length clock arm posts. As it so happens you need the long one. l am now happy to announce that third time lucky, l can once again time travel. Broken. Fancy mechanicals. It works with such precision when it does work though not in the Rolex kind of way. Rear now looks like this. Altering time and battery change is easy. And it now has a second hand.
