Explore an intense texture crafted in an array of fine finishes on a black metal canvas. Introducing the GMW-B5000, a true heir to the first-ever G-SHOCK in a multi-finish black metal design. The art of timepiece finishes is on full display with this watch. Honing finishes feature prominently on the bezel and band, with sides treated in a hairline finish and beveled band surfaces, screws and buttons treated in a mirror finish. The entire watch is then coated in black ion plating. Finally, the top surface of the bezel is polished once again in a hairline finish to expose nearly all of the stainless steel beneath the ion plating. Ion plating one shade lighter than conventional black integrates the re-exposed stainless steel of the bezel seamlessly into the overall design for a sophisticated, well-balanced, and singularly intriguing timepiece.
A SQUARE CASE WITH A
FULL-METAL SHOCK-RESISTANT STRUCTURE.
ACHIEVED THROUGH SYSTEMATIC EVOLUTION FROM ONE STAGE TO THE NEXT.
The first G-SHOCK model DW-5000C was born in 1983.
Its symbolic square design is reinvented with a full-metal shock-resistant structure and the latest advanced functions, including Smartphone Link.
The only truly tough watch continues to challenge greater heights.
The stainless steel bezel and band feature black IP in a lighter tone compared to the conventional black IP (of the GMW-B5000GD-1).
The chic, matte black on the honed surface adds sophistication and balances well with the silver of the stainless steel that remains after polishing.
The entire bezel is thoroughly honed, with a hairline finish applied to the sides and a mirror finish to the screws and buttons.
The entire bezel is then given a black IP and the top surface only polished again with a hairline finish.
This removes most of the black IP down to the stainless steel, while leaving the IP in the engravings.
The black base colour treated with different finishes gives the watch a uniquely appealing look.
The band pieces are honed, with different finishes applied to the details to accentuate the beauty of metal.
The links and buckle receive a hairline finish on the sides, while a mirror finish is applied to the bevelled surfaces.
The screw-back of the watch case is mirror-finished and then receives a DLC coating.
Buffering components made of fine resin are installed between the stainless-steel bezel and case. With its metal exterior in the original form of the very first G-SHOCK, the watch makes the most of its shock-resistant structure.

Square face design true to its roots
A true heir to the distinctive identity of the first-ever G-SHOCK, the iconic brick pattern of the original design adorns the dial. Features a super-twisted nematic (STN) LCD for superior contrast and a wide viewing angle.

Solar-powered timekeeping with Bluetooth® and radio control for enhanced accuracy and reliability
A fusion of strength and beauty.
Bezel case
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.
Solid feel and superior wearing comfort.
Black IP Metal band
The design of the first model’s resin band is reproduced by applying dimple-processing to the (black IP) 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.
Inner case
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 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.
