I am so sorry to hear about your loss. You should prepare a good ebay search in case the thief tries to sell the watch. Use ebay Germany for the search. If he keeps it for himself, there's nothing you can do to find it. But with your ss# on the watch, there's a fairly good chance that you can find it. You might also want to let some of the bigger swiss antique watch dealers know of your loss so that they can keep an eye out for it.
