Anyone have a quick clue or link to a Wikihow on potential causes for the date wheel on my older 7002 to have stopped? For a bit there, it was having trouble advancing if I needed to set the date, like it would take two turns to get it to go once. Now, it's halfway onto a date, and it just sits there. Watch works fine, keeps great time. I'm hoping to have a clue before I dive in, not liking the idea of having my first foray into this watch be blind.
