I rock a Rolex Sea Dweller Deepsea. Not my photo obviously but this is the watch. It's the most water resistant watch in the world, resistant to 3900m under the sea. Which is about 8x deeper than anyone has ever dived, haha.
And I don't even dive. Looks cool though eh?
This is the first good watch I've ever owned. Next off I'm looking for something very different: A Christiaan Van Der Klaauw. He makes these incredible, intricate astronomical timepieces. Check it out:
