I have picked up a Waltham Crescent st watch with an up & down winding indicator . The watch runs and stops it does not look dirty but i notice that while the watch is running the winding indicator does not move much if at all. Before I take the watch apart for inspection and cleaning can someone explain how the winding indicator is driven? and if the mainspring is set will that effect the indicator? any advice would be of help. Thanks

Haven't look at one of these for a long time, but from memory the wind indicator cog on the dial plate drives of the mainspring barrel, I think:???:.
