Casio's Edifice EQB800DB-1A features Bluetooth smartphone mobile link watch with chronograph and Accurate Time System feature. This dynamic, intelligent wristwatch is able to automatically retrieve world time information through a Bluetooth connection with a user's phone. Four different times a day it will access time servers located on the Internet to get an accurate reading of current home times as well as world time. The chronograph function, specifically its design, is just as cool with a color scheme that resembles a speed-indicating tachymeter.
