Description
The Casio G-SHOCK GA100-1A2 combines bold oversized styling with the rugged durability that has made the GA-100 series one of the most recognisable G-SHOCK collections worldwide. Featuring a matte black resin design accented with metallic blue highlights across the dial, this model delivers a sporty and high-impact look suited to everyday wear, streetwear, and active lifestyles.
With a case size of 55 × 51.2 × 16.9 mm, the GA100-1A2 offers strong wrist presence and excellent readability. The large layered dial design creates depth and texture across the face, combining analogue hands with digital displays for a modern industrial-inspired appearance. The black and blue colour combination gives the watch a clean athletic aesthetic that pairs easily with casual outfits and sport-inspired styling.
Built with G-SHOCK shock-resistant construction and magnetic resistance, the watch is designed to handle demanding daily wear, outdoor activities, and active environments. The durable resin case and band provide lightweight comfort, while 200-metre water resistance makes the watch suitable for swimming, travel, and everyday exposure to water.
The analogue-digital display includes practical functionality such as World Time across 29 time zones, a 1/1000-second stopwatch with speed indicator, countdown timer, five daily alarms, and full auto-calendar functionality. An LED light improves visibility in darker environments, while Neobrite hands provide quick readability at a glance.
Known for its oversized design and rugged performance, the GA-100 series remains a favourite for people wanting bold styling combined with dependable everyday functionality. Combining sporty colour accents, durable construction, and practical features, the Casio G-SHOCK GA100-1A2 delivers reliable performance with iconic G-SHOCK attitude.
