Dive watches are meant to be tough, not surprised it's still looking great!

As for cleaning, sometimes vinegar or isopropyl will loosen things that soap doesn't, but to really get nooks and crannies, your best bet is a quick trip to a jeweler or buying some specialized tools. If you know your local jeweler or go to the place you bought the watch, they'll often do a quick outer cleaning free.
