600D watch, the latest addition to the Edifice series of high-performance watches that combine dynamic styling with cutting-edge technology. The EQB-600D links to a smartphone and boasts a new multidimensional inset dial featuring an Earth motif that delivers the next step in the evolution of world time through an imaginative display. Casio introduced the Global Time Sync concept to drive development of analog watches for today's global age. Under Global Time Sync, Casio has developed G-Shock and Oceanus watches with GPS Hybrid Wave Ceptor technology that receives both GPS satellite and radio wave time calibration signals, and Edifice watches that link with a smartphone to set the time for some 300 cities across the world. These watches are gaining acclaim as advanced time keeping systems that deliver accurate time anywhere in the world. The EQB-600D features 3D Globe Dial, a dome-shaped multidimensional inset dial with an Earth motif that displays the world time in an imaginative and aesthetically pleasing way. The finely detailed Earth motif is realized using the advanced molding techniques of Yamagata Casio Co., Ltd., the production base of Casio in Japan. A polarized deposition finish makes the color change at different viewing angles, adding further refinement to the watch. 3D Globe Dial works in conjunction with the world time shown on the inset dial at the 8 o'clock position, and it gradually rotates once every 24 hours just like Earth. The curved inset dial hand indicates the time zone for the world time city. When the inset dial hand is in the upper half of the 3D Global Dial, it indicates that it is nighttime (between 6:00 p.m. and 6:00 a.m.) in that time zone, and when in the lower half, it indicates that it is daytime (between 6:00 a.m. and 6:00 p.m.) in that time zone. This provides a visual daytime and nighttime indication, in addition to the time indication. Casio developed the Accurate Time System, which further extends the time-setting features when linked to a smartphone. This system is incorporated into the Casio Watch+ smartphone app, which links with the EQB-600D. The system connects to Internet time servers which supply time data, matching the data to a proprietary map database to obtain accurate times by extracting time zone data in the current location and daylight savings data.
