Casio Releases EDIFICE Watches That Link with Smart Phone That is Enable to Access 300 Cities World Wide.
Bluetooth® Smart Connectivity Allows Times to Be Adjusted with Local Time Information

Tokyo, September 5, 2014 – Casio Computer Co., Ltd., announced today the latest models in its EDIFICE lineup of metal watches designed to convey the concept of "Speed and Intelligence." The new Smartphone link EQB-500 watches feature dramatically improved usability of world time functions.

In 2012, Casio released a G-SHOCK watch that pairs with a smartphone using Bluetooth® Smart technology to notify the wearer of incoming calls or emails. Since then, Casio has been using this technology to create all new ways to use its watches, including PHYS watches that display fitness data and G-SHOCK watches that can control a music player.

Now, Casio is releasing the new Smartphone Link EQB-500 lineup of EDIFICE watches featuring all the benefits of a quality wristwatch, including a solar-powered movement, waterproof toughness and a refined design that only a metal watch can offer, while also enabling smartphone connectivity. This greatly improves the speed and ease of access to world time information because users had to calculate and manually set the time to the time zones of different cities.

Each watch can connect to a smartphone*1 with just one push of a button and automatically adjust the time to the local time while correcting for daylight savings time if necessary. Furthermore, users can easily set the time corresponding to 300 cities worldwide just by selecting from maps and city lists included in a Casio smartphone app. The center-positioned hour and minute hands along with one of the inset dials not only simultaneously display the time for two different cities, but can also switch the time being displayed on each with only a push of a button. This lets users quickly check the time in their home country as well as the time in the locations of their business trips and holidays.
*1 Requires installation of CASIO WATCH+ app, which is available for download from the App Store for iPhone or Google Play
CASIO WATCH+ app will be made available for download concurrently with the release of the watches.





Looking ahead, Casio intends to develop highly functional new analog watches based on its "global time sync" development concept. By enabling these watches to connect to smartphones, Casio will equip them with next-generation world time functions that are simple to operate, making it easy for users to check the time in places all around the world without having to think about time zones.
