CASIO EDIFICE Smart Phone Link EQB-900D-1AJF Silver

The smartphone link series*1 of the "Edifice", which continues to evolve as an advanced, highly functional metal chronograph, is now available in a smaller size, the new EQB-900. The new model is the smallest in the series in both width and thickness. The EQB-900DB with a blue IP-treated bezel and the EQB-900D with a silver bezel are two new additions to the EQB-900 series. In addition, the indexes and dials have been designed with a powerful presence. Despite being the smallest in the series, the new model has a bold design that does not lose its impact. In terms of function, the new LED light at the 6-7 o'clock position on the dial ensures that the watch is legible day and night. It also features an automatic time correction function that automatically updates daylight savings time and time zone information four times a day via a smartphone, and a world time setting function that allows users to set world time by simply tapping on the app from approximately 300 cities. This accuracy is further enhanced by the Accurate Time System*2. The system accesses a time server that provides time information on the Internet and compares it with a proprietary database to extract time zone information and daylight savings time information for the current location and obtains highly accurate time. This allows the watch to keep accurate time anywhere in the world. These functions are powered by tough solar power, so you can use the watch without having to replace the batteries on a regular basis. A new chronograph model with advanced functionality and practicality and the smallest size in the series is now available. (This product is EQB-900D.)
1 The dedicated app "CASIO WATCH+" must be downloaded.
2 Accurate Time System is a time correction system that captures the time from time servers around the world and combines it with Casio's proprietary database to generate the current time.
