Just ordered a Casio G-Shock Gulfmaster for myself and man I haven't been this excited in a while.
Solar powered, time synced to the nearest Atomic Clock (my favorite feature), built in altimeter,barometric pressure, compass and temperature, plus all the usual chronograph functions. The watch also tracks the tides and phases of the moon and of course it's a G-shock so I can be as rough as I want with it and not have to really worry about it holding up to the abuse. Now that is what I call a smart watch.
I'll be in the Caribbean next week for the holidays and plan to put those tide and barometric pressure sensors to the test while searching for pirates.
