GA Series

The G-Shock GA series (excluding the GA-110 series) is a diverse collection of Casio G-Shock watches known for their rugged durability and versatile analog-digital or analog-only designs. Built with G-Shock’s signature shock resistance, these watches are engineered for tough environments, offering water resistance up to 200 meters, world time (typically 48 cities), stopwatch (1/1000-second precision), countdown timer, and multiple alarms. 
Popular models like the GA-100, GA-200, and GA-700 feature bold aesthetics, with large cases, vibrant color schemes, and LED illumination for enhanced visibility. Many include magnetic resistance (ISO 764 standard) for added durability. The GA series blends style, functionality, and G-Shock’s iconic toughness, making it ideal for sports, outdoor adventures, and everyday wear for a wide range of users.


  • GA-100: A classic big-case analog-digital model with a bold, steampunk-inspired dial featuring layered details and gear-like hands. Introduced around 2010, it's praised for its legibility and simplicity, ideal for everyday toughness and streetwear.
  • GA-150: Oversized round case, rugged 3D dial with bold analog hands over digital display; features magnetic resistance, 1/1000-sec stopwatch, 5 alarms, world time; durable resin case with textured bezel.
  • GA-200: Slimmer profile with a carbon fiber-reinforced resin case for lightweight durability. Known for its minimalist yet bold look, it adds vibration resistance and is favored for active lifestyles.
