* Due to the screw-lock construction of the case back, the logo and lettering may not match up perfectly with the dial.
Ongoing internal evolution.
Progression to a new-generation engineG-SHOCK has introduced one pioneering functional innovation after another.
These have included light functions to enhance the visibility of the dial, Tough Solar power supportings table operation of multiple functions, standard time radio wave reception for accurate timekeeping and Bluetooth® communications for versatile multi-function control.
The countless challenges we faced in our mission of functional evolution have now been overcome.
The new GMW-B5000 represents the culmination of G-SHOCK’s solutions.
The heart of a multi-function watch.
LSI layout
The mounting position of the standard time radio wave antenna is calculated to ensure stable radio reception sensitivity inside a full-metal case. In this and other ways, the highly precise LSI design has solved the problems associated with a metal exterior and multi-functionality.
Breakthroughs in functional innovation.
Dedicated design module
We have leveraged our proprietary high-density mounting, miniaturization and power-saving technologies to install multiple functions without increasing the watch’s size. This innovative functional evolution has included such achievements as simultaneous installation of Bluetooth® communications and radio-controlled, solar-powered timekeeping.
Challenging absolute accuracy.
Bluetooth® + Radio-controlled, solar-powered timekeeping
Time correction is conducted by either Bluetooth® communications or standard time radio wave (Multi Band 6), depending on the circumstances. Reception of the most recent time zone and Daylight Saving Time information assures that the correct time is displayed at all times.
Evolving dial-lighting technologies.
Full-auto LED backlight (Super Illuminator)
An LED backlight illuminates the LCD with high-brightness light. It detects ambient light in the surroundings automatically, and switches on with a tilt of the wrist in the dark. New features such as fade in/out and white/orange lighting add further versatility.
Advanced digital display.
STN LCD
An STN LCD has replaced the conventional TN LCD to take advantage of its higher contrast and wider viewing angle. The face, including the logo and function display, is completed in a design mirroring the layout of the first model.
Enhanced visibility.
Film solar panel
The material employed for the solar panel has been changed from glass to an easily processed film. An aperture is opened in the center of the panel to suppress reflections of external light and improve the LCD’s visibility.
Legacy of the universal ratio.
Display aspect
The LCD’s approximately 16:10 aspect ratio approaches the angle of human vision. Adopted in pursuit of clear visibility, this ratio has been handed down from one model to another since the origin to benefit from its closeness to the Golden Ratio, which is considered to represent the most beautiful proportions in nature.
