Casio's latest G-Shock has gone on a bit of a diet losing the traditional bulk in exchange for a slimmer case that is just 11.8mm thin. The 45.4mm watch has a hybrid analog/digital design and features 200M water resistance, world time with 31 timezones, chronograph functionality, five alarms, an automatic calendar, a three-year battery life, and carbon core guard construction that features a bumper made out of carbon composite. Oh, and it's pretty damn affordable too.
