I would go to a watch forum, like
Watchuseek, The Most Visited Watch Forum Site ... In The World. which is the PP of watch forums.
You could maybe try consignment or to a used watch guy, but my guess is you would get pennies on the dollar.
Hell, you might be able to sell it here. Find out what a consignment place would give you and what they are selling for used from a dealer, then price yours somewhere in the middle.
