Casio to Release OCEANUS Watch with Striking Recrystallized Blue Sapphire
Receives Both GPS and Radio Wave Time-Calibration Signals

BASEL, March 18, 2015 – Casio Computer Co., Ltd., announced today the latest addition to the OCEANUS line of solar-powered radio-controlled metal watches designed to capture the essence of elegance and technology. The OCW-G1000E features recrystallized blue sapphire*¹ on the crown and pipe.
*1 Recrystallized blue sapphire is a man-made gemstone with the same chemical composition as the real article, realized through Kyocera Corporation's proprietary gemstone synthesis and crystallization technologies. It is notable for its beautiful color and having the same hardness as genuine sapphire.

Starting in 2014, Casio has been creating new products based on its "Global Time Sync" development concept of offering analog watches for a global era. From G-SHOCK and OCEANUS watches that receive Global Positioning System (GPS) and radio wave time-calibration signals, to EDIFICE watches that can be linked with smartphones, Casio watches are gaining acclaim as advanced time keeping systems that deliver accurate time anywhere in the world, with just one push of a button.

The new OCEANUS OCW-G1000E watch expands the lineup of watches based on the "Global Time Sync" concept and is based on the popular OCEANUS OCW-G1000 watch that has a hybrid timekeeping system. The bezel features navy blue ion plating, while the crown and pipe at the center of the second hand are rendered in recrystallized blue sapphire to give a deep blue look that is characteristic of the OCEANUS line. The dimensional numerals at the 12 o'clock position feature elegantly tinted white mother of pearl, while the inside rim the bezel is finished in elegant gold-colored plating that handsomely complements the blue hues.

Just like the model it is based on, the OCW-G1000, the new OCW-G1000E watch offers superb functionality and corrects the time according to the region where the user is, with either GPS or radio wave time-calibration signals, in as little as only seven seconds with just a push of the button. The new watch also features Dual Dial World Time, which simultaneously displays the time in two different cities. The face features dual-curved sapphire glass with an anti-reflective coating on both sides for high visibility, and the case has been finished with Sallaz polishing that gives a lustrous finish and a look that is all OCEANUS.
