I was going through this thread looking for infos about the different movements. And I was suprised to read that the ETA 7750, "Valjoux" movements must NOT be set the date between 8 PM and 2 AM, or you will damage the movement.
Is it true ? To be clear about (and to be sure) this ? So you need to first set the time to 5.00 am (for example) then set your date then set your real hour (11.25PM for example) to avoid troubles with the movement ?
