Help my beloved submariner got water inside

[bimmerboy]

I went for a swim Saturday night after work with my 16613 TT submariner and half and Hour later my worst nightmare occurred after glancing down at my wrist my date window was completely fogged up. It's been 24 hours and now the date window has cleared although I still can see tiny little water drops around the rehaut. What should I be doing I've left the crown open and stopped the movement. Please let me know as I am becoming very nervous.
