waterproofness:
I regularly dive, and I have a professional wrist diving computer. In recreational diving, like PADI or others, you can dive 30/40 meters deep with air or nitrox.
A watch for 50 m (165 ft) is allowed for swimming or showering with it.
Good watches for dive put its range in pressure, (1 atm for 10 m deep).
Celestial navigation:
I put my watch in UTC and some time in UT1, and the more complicated for me is to synchronize it with hourly signals. All I have are not easy to set.

And a side note on waterproofness: I read a watch spec recently that said it was "waterproof to 330 meters" That's roughly 1000 feet. Talk about overkill -- I believe that even with the latest and greatest specialized diving apparatus, humans are limited to about 400 ft.
