Just scored this very cool, unique Clinton World Timer with a dive bezel. The seller (on the 'Bay) was very communicative and obviously put some work into restoring the watch, including a "minor service". Everything feels buttery smooth.
My vintage watches are mostly hand-wound and I was wondering what people's experience is with this era (60s/70s) of automatic movement? The seller said that the rotor was "balanced and quiet", which it is, although I've noticed that it barely spins at all. My modern Monaco is very noisy, as are my 70s Citizen Challenge timers!
He suggested jump-starting it with a hand-wind, which works, of course, but when I give it the kind of shake I give to my more modern automatics, it only seems to tick for a minute or two. After a hand-wind, it goes strong.
The seller said that modern rotors are heavier and weighted better - I assume that means they spin more freely/easily - and thus will wind a watch without the help of a hand-wind.
It's common knowledge that lower-end automatics from the 60s/70s will need a hand - literally - to wind the movement when it hasn't been worn in a few days - is this what I'm dealing with? In other words, I shouldn't expect to just pop it on fully unwound, give it a little wiggle and go, right?
Thanks in advance,
