That depends on the type of watch.
If you've got a proper 200m pressure rated watch for example, you have to 
(or should) inspect or (more usually) replace the o-ring, grease it up 
again, and do a full pressure test after it's all done.

If you don't like changing batteries, Casio (and probably others) have 
watches rated for a 10 year battery life.
