That’s a very cool description of the these watches they have always seemed to be from the future if you look a picture of these movements with the transistors and coils and the tuning fork they were so far ahead of time no pun intended I really like to wear them..... and of course they still can be picked up cheaply
One of them is fast. Or slow. Or both. "Man with watch, always know exact time. Man with two watches, never quite sure."
