I had a debate, at least in my mind, about whether to show certain executions of the Carreras based primarily on the execution of the dial or on the execution of the hands. We see later dials with earlier hands and we see earlier dials with later hands . . . there are scenarios to explain both variations. In the end, I go with the dial, as a more fundamental, permanent element of the watch.

I also thought about the Tachy rings, but these seem to be the least "permanent" of all . . . easily and often replaced. We also have the possibility that Heuer was using "anything with anything", in certain periods, so it all becomes a bit of a jumble.
