Steve Zissou would sport the blue Freestyle Ballistic Diver watch. Not only does it look nautical, it is nautical. There's a screw-down crown, so it resists water to 660 feet (200m), which is deep. The nylon strap is stronger than a Jaguar shark's bite (maybe) and it secures at four different points, military-style. Get the job done, and look like a Navy captain on deck.
