Evolution back to the Origin
The only truly tough watch continues to challenge greater heights.
Toughness in Metal.
Newly developed structure.
Achieving G-SHOCK's unique shock-resistance capabilities in full metal required a complete redesign of the external structure, including the case, band and buttons.
A new internal structure employing fine-resin cushioning material was developed to offset the more powerful dropping shocks resulting from weight added by using high-strength stainless-steel parts.
Shock resistance achieved with a full-metal case.
The new shock-resistant structure
Fine-resin cushioning parts are inserted between the bezel case and the inner case. Besides achieving a highly accurate fit, this structure responds with reactive force to ease shocks when tiny protrusions in the cushioning material are compressed.
Fortification of moving parts.
Band connection structure
The double-lug structure conventionally used to connect the band to the case has been redesigned to create a three-pronged lug structure. Shocks to the connecting pipes and button shafts are dispersed, and the band attachment is reinforced.
Protecting the button shafts from shocks.
The specially developed button structure combines large cylindrical forged buttons with internal pipes that guard the vulnerable button shafts from the inside against lateral shocks.
Screw-lock case back Increased air-tightness specifications.
Screw-lock case back
The airtight, heavy-duty screw-lock case back replicates the first model’s. The slanted surfaces are mirror-finished, and DLC (diamond-like carbon) treatment is applied overall for enhanced wear resistance.
Pursuit of extreme functional beauty.
Our commitment to quality.
The use of metal material requires the most advanced processing technologies to reproduce the design of the first G-SHOCK model. We apply leading-edge forging and cutting technologies in our commitment to evoking the beauty of finely inscribed details and to attaining a finish that maximizes the beauty of the metal textures.
The result is a level of quality that sets a new standard for tough watch design.
Bezel case A fusion of strength and beauty.
After sculpting the form through repeated forging, cutting and polishing, artisans apply mirror polishing and hairline finishing to the surfaces in pursuit of flawless beauty. The case back surface is finely machined to remove any unevenness and assure an accurate fit with the cushioning parts.
Metal band Solid feel and superior wearing comfort.
The design of the first model’s resin band is reproduced by applying dimple-processing to the stainless-steel band pieces. Each piece is alternately pressed and polished in an unstinting effort to assure beautiful finishing that extends to the bottoms of the dimples.
Extending attentive workmanship to unseen parts.
After a process involving 10 or more forging and cutting steps, a complex form with integrated lugs and complicated shapes comprising various fitted and cushioning parts takes shape. Precision parts facilitating smooth, accurate assembly are produced.
Maintaining G-SHOCK’s origins without change.
Original square design
The design of the first G-SHOCK model has been maintained continuously from the origin. Casio’s efforts in pursuit of universal usability have encompassed the structure with its undivided attention to shock resistance, the large LCD offering excellent visibility and the minimalist form that eschews any interference with wearing ease and comfort.
Ongoing internal evolution.
Progression to a new-generation engine.
G-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 GMWB5000 represents the culmination of G-SHOCK's solutions.
LSI layout The heart of a multifunction watch.
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.
*Multi Band 6 not available in NZ
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.
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.
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.
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.
