G-Shock’s most popular large case analog/digital series introduces a matte black watch, the GA100MB-1A. The face and band are matte black with green accents which highlight the toughness and coolness of G-Shock.

The G-SHOCK has long been known as the watch that pushes the limits of shock resistance and water resistance. Now these models test new limits for battery life. These models include the distinctive G-SHOCK design and powerful G-SHOCK functions plus a design that enables a 10-year battery life. Functions include e-DATA MEMORY for storing URLs and e-mail addresses, 27-city World Time, multi alarms, and other features that come in handy during work and play.

From G-SHOCK, the watch that delivers the ultimate in modern personal timekeeping, comes a GULFMAN model that packs powerful features and functions into a tough rest-resistant configuration. All external metal parts, including screws, back cover, buckle, and even button shafts are made of titanium alloy for total protection, even in seawater environments. The band is secured to the case by milled titanium alloy screws, while the form of the forged titanium alloy back provides outstanding impact resistance. The band is configured so it does not adhere to the wrist when wet. Functions include Tide Graph for current tide conditions at a glance, Moon Phase Graph for graphic display of moon phases, and Dual Illuminator for simultaneous illumination of the display and its periphery.

Milled Band Screws
Special Titanium Alloy Button Shafts

DUAL ILLUMINATOR
Dual EL panels provide simultaneous illumination of the LCD panel and the dial for better readability when available lighting is dim.

RUST-RESISTANT STRUCTURE
Built specially for seafaring use, Gulfman employs titanium construction for all metal parts that come into contact with air, from the bis, case back and buckle to the button shafts. A titanium bis has also been adopted for the band attachment to provide rust-resistant countermeasures down to the smallest detail.

NEW MUD RESISTANCE + TRIPLE SENSOR
This new MUDMASTER model was created especially for this whose work takes it into areas where piles of rubble, dirt, and debris are present. A special vibration-resistant construction lets them stand up to wear while operating cutters, crushers, drills and other heavy machinery to clear way large obstacles. This is CASIO's first analog watch to come with Mud Resist construction, which helps to ensure that nothing gets into the watch when down and dirty work takes you deep into the dirt and sludge. Multiple gaskets are used on the pipes that guide buttons and shafts, which keeps mud out. These pipes not only act to protect buttons from impact, they also enhance button operation. The screw-in force of the screw lock bezel on an internal gasket further increases mud resistance.

The large-case GA-110 analog-digital combination watch takes on a new look with the addition of metal elements that give the faces an industrial feel. The new design uses shiny metal for hour markers and the dial, in addition to the hour and minute hands.

Introducing a collection of new G-SHOCK models whose 35mm diameter faces and large cases give them a look of power and strength.
Dial rings and raised hour markers create three-dimensional depth that gives the face plenty of character.
The popular G-SHOCK three-dial face design incorporates one analog dial in the center, with digital dials on either side.
These watches are designed and engineered to deliver outstanding shock resistance and water resistance, as well as anti-magnetism.
Over-sized buttons come with a checkered anti-slip surface to make operations fast and sure.
1/1000-second stopwatch, velocity indicator, World Time, 5 alarms and much more provides these models with unmatched function and performance.

This new MUDMAN model is the first one to be equipped with a direction sensor and thermo sensor that help you keep your bearings whenever you adventure into parts unknown. The touch of a button goes directly into the Compass Mode from any other mode. A Moon Phase graph gives you an idea of whether the nighttime hours will be dark or light. A declination function even makes it possible to adjust the watch's magnetic north direction reading so it indicates true north.
All of this plus Tough Solar to keep everything working, and total shock and mud resistance to keep everything well-protected.

Two new bold analog-digital combination models in a selection of two-color styles: red and black or white and black, both in an all-matte finish.

Camouflage Series
From the popular big, bold GA-100 Series comes a new collection of models that feature a camouflage pattern face. Basic black or gray coloring is offset by the metallic camouflage pattern of the face, which is further accented by the silver or gold coloring of the hands and hour markers.

Introducing GULFMASTER, the new G-SHOCK Series that’s designed and engineered with the maritime adventurer in mind.
GULFMASTER includes the first G-SHOCK models to incorporate both Triple Sensor Version 3 and Smart Access in the same watch. In addition to barometric pressure, altitude, bearing, and temperature readings, these new models also feature Tide Graph and Moon Age capabilities to help keep you in close touch with your natural environment. Sudden extreme changes in barometric pressure are alerted using a dial hand, LCD display, and alarm. Double LED lighting illuminates the LCD, and also adds a face light at 6 o’clock to keep information bright and easy to read even in total darkness.
The designs of these watches have been modeled after the look of shipboard instruments to create an attractive marine look. Large buttons are provided for critical light and sensor operations to help make operation easier and more intuitive.
All of this and much more makes all of the models in the GULFMASTER Series the logical choice for the maritime adventurer who desires something extra in performance and overall toughness.

From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes G-STEEL, a watch series with a new "layer guard structure".
Different materials are used for the bezel to create a two-layer structure that adds a new dimension of shock resistant. For models that use stainless steel in the upper part, shock absorbing resin is employed in the lower part. If resin is used in the upper part, fine resin is used in the lower part to cushion against impact from the upper part. This also has made it possible create a wide range of different designs.
The GST-S110 model expresses the hardness and beauty of metal.
A hand shift feature temporarily moves hands out of the way with the press of a button for easy reading of digital display contents, while double LED face illumination keeps information easy to read at all times.

This model combine the best of digital and analog in tough G-SHOCK designs. Buttons are recessed to protect them from impact, and variations are available in a choice of three sporty bezel colors: silver, red, or blue.

A slapshot by a professional hockey player was all it took to send this G-Shock into history and into a goalie’s mitt, literally. If it can handle a slapshot, it can handle your life. We like to refer to it as the quintessential G-Shock.
