■ Product Overview
The CASIO G-SHOCK GA-2100SU-1A is an international analog-digital watch from the 2100 Series.
This utility-color model combines a black case and resin band with an olive camouflage pattern printed on the octagonal bezel. Its slim profile and practical color scheme complement casual, street, and outdoor-inspired styles.
■ Key Features
Camouflage Bezel Design
Features an olive camouflage pattern printed on the black octagonal bezel. The pattern is applied to the bezel rather than the entire watch.
Carbon Core Guard Structure
A carbon fiber-reinforced resin inner case protects the module while helping maintain a slim and lightweight profile.
Shock-Resistant Construction
Designed to withstand shocks and vibrations associated with everyday and active use.
Analog-Digital Display
Combines analog hour and minute hands with a digital display for timekeeping and additional functions.
Neobrite Luminous Coating
Neobrite is applied to designated analog display components to improve visibility after exposure to light.
Double LED Super Illuminator
White LEDs illuminate both the analog dial and digital display. The illumination duration can be set to approximately 1.5 or 3 seconds.
200-Meter Water Resistance
Provides 20-bar water resistance for everyday use and water-related activities, subject to the precautions in the instruction manual.
World Time
Displays the time in 48 cities across 31 time zones, plus Coordinated Universal Time. Daylight-saving time can be enabled or disabled.
Stopwatch
Includes a 1/100-second stopwatch with elapsed-time, split-time, and first/second-place measurement modes. The maximum measuring capacity is 24 hours.

■ Important Notes
This listing is for the GA-2100SU-1A utility-color model with an olive camouflage pattern printed on the black bezel.
The GA-2100SU-1A should not be confused with newer GA-2100CM camouflage models or standard solid-color GA-2100 variations.
This is an international model. Packaging, documentation, model-number suffixes, and warranty coverage may differ from Japanese domestic versions.
This is a new product. It is not pre-owned, renewed, used, or refurbished.
The manufacturer currently identifies the GA-2100SU-1A as an older model. This classification does not indicate that the item is used or refurbished.
Neobrite is a luminous coating that stores light and glows temporarily in dark conditions. Its brightness and duration depend on the amount and duration of prior light exposure.
Neobrite and the white LED Super Illuminator are separate visibility features.
The 200-meter water-resistance rating does not mean that the watch is certified as a professional diving instrument. Follow the included instructions and do not operate the buttons underwater unless expressly permitted.
Battery life is an approximate value and varies according to alarm, illumination, and other operating conditions.
The position and appearance of the printed camouflage pattern may look slightly different depending on the viewing angle and lighting conditions.
Product colors may appear different depending on lighting and display settings.
Specifications, packaging, and included documentation may change without prior notice.
