Regulating another mechanical watches

[Aspirin]

From the forum here I got some knowledge useful to regulating a Rolex as below, for another mechanical watches if applicable?
1. To gain a few seconds, lay the watch flat face-up overnight.
2. To lose a few seconds, lay the watch vertically with the crown downwards overnight.
3. To lose a few more seconds, lay the watch vertically with the crown up overnight.
