I've been looking at these for a while and thanks to some of the people who posted theirs in a different post I have come across this mint example. But it was dear for what is basically a fat upside down pocket watch with a fat magnet stuck on the back! But it is lovely and it will be used in my 1973 Triumph GT6. (all the clocks in the car happen to be made by Smiths and are black as well).
