Casio Edifice EQB-600D-1A2

The CASIO WATCH+*1 app that makes it possible for the EQB-600D to link with a smartphone now comes with a new Accurate Time System to help keep you on time all the time. Smartphones maintain accurate timekeeping by using their networks to access time servers around the world. The EQB-600D models automatically sync their time settings with a smartphone four times a day and update their time settings accordingly.
In addition to a World Time 12-hour dial that shows the current time in a second location, a 3D Globe Dial at 3 o'clock shows an image of the Earth, looking down from above the North Pole. The precision engineering capabilities of Yamagata CASIO were tapped to create a 3-dimensional dome dial that has a unique curvature. The 3D Globe Dial can be used to check your current World Time zone, and to determine whether the indicated time is during the daytime or nighttime.
The Mobile Link function employs Bluetooth SMART technology. After downloading and installing the CASIO WATCH+ app, you will be able to link to a supported smartphone*2 and perform watch operations from there. You can also select from approximately 300 cities registered in the app, and display the selected city's time with the World Time dial. You can even perform a watch button operation to sound your phone's ringtone so you can easily find it.
Though the designs of these watches are powerful and bold, they are a mere 13.3 mm thin (0.8 mm thinner than the EQB-500D), for a great look and a comfortable fit to the wrist.
