don't really understand the romance about the rep mechanical movements.
used movements are not really state of the art.
movements used are not very expensive.
chances are slim they run exactly on time.
the powerreserve last only a day or so.
so you continuously are resetting the time and date unless you have a watch winder.
wonder if you could recognise what's in it from the outside.
these reps are still make beleive watches.
just bought a PO 45 eta and a SFSO eta recently.
I'm very happy with them but one is running +10 secs per day the other -5secs per day.
I switch watches each day. Sometimes the powerreserve is just enough but most of the times I have to reset the time each morning.
