I owned a couple of Omega automatic watches which battery less, were therefore
environment friendly pieces on top of that btw. All are/were sharp on the dot.
Lost one recently … but I no longer need it as I’m now retired and live by the
seasons and sunrise and sunsets ;-)
Did I ever miss anything for the want of a second during my inactive time
working?
Thinking ….
