Recently got a Longines Ultronic in impeccable condition.
Since this is an ELECTRIC tuning fork watch I heard the battery lasts only about 1 year if lucky.
If that is the case, then I would like to interrupt the battery power while Im rotating between watches.
Im concerned though: will pulling the crown out NOT save battery (it seems to stop the second hand). I've heard this could damage the movement.
Here's some pics:
