Can you Overwind ETA 2824?
You cannot overwind an ETA 2824-2 movement. If the movement is completely wound down usually 40-50 turns of the crown will fully wind it. More winding will not hurt the movement. Automatic watches have mechanisms which allow the mainspring to slip inside the barrel when further wound in a fully-wound condition.
Can you manually Overwind an automatic watch?
If you have an automatic watch, it’s not possible to overwind it. If the watch has full power, the rotor inside the timepiece will simply stop spinning. Automatic watches are designed to stop powering the mainspring when it can’t be wound anymore. It’s not possible to over-wind an automatic timepiece.
How often should you manually wind an automatic watch?
Try to wind your watch once a day. A watch typically keeps best time when the mainspring is above half tension. The typical watch has about a two-day power reserve so winding it up before you strap it on each morning is a good habit to form.
