How bizarre,
my own experience with a watch getting its innards wet were a rapid demise of all chrono functions (it was an early seventies Breitling Chronomat), followed by a grinding halt of the rest within 3-4 hours.
It was taken to a dealer the following day, who immediately removed the movement, and cleaned it in light oil. It was then forwarded to his workshop, where it required a new mainspring and a number of smaller components that had severe corrosion. A very expensive swimming pool visit.
I would guess in your case that there was very little moisture entered the case (due to the fact that yours is still working) and it was an unfortunate coincidence that the hand and button fell off at the same time (did you try and 'shake out' the moisture, maybe a bit rougher than you would normally handle your watch?).
As to the missing circlip, God forbid that Omega would produce a 'Friday afternoon' watch.
