G-Shock GA100-1A2

$175.00$289.00

Living up to G-Shock’s reputation for big case designs, comes a revolution in case size with the introduction of the X-Large G.

This Ana-Digi, “three-eyed” monster measures in at a whopping 55 x 51.2 x 16.9mm size, with an attention to detail that is second to none. Large anti-skid buttons provide easy operation, embossed indexes give a 3-D look, and a rivet bezel design adds strength to its overall appearance.

Explore models like the sleek GA100-1A1 for bold durability or the striking GA100B-7A in a fresh white design. For a pop of color, the GA100-1A4 delivers a fiery red accent, while the GA100CF-1A stands out with its camouflage pattern. If you’re after a unique touch, the Blue Paisley GA100BP-1A offers a creative flair to the X-Large G lineup.

What to do with Broken Watches? 

G Shock Battery Replacement

G Shock battery life ranges from two to six years, depending on how often you use the alarm or the backlight. Frequent use of either feature drains the battery pretty fast hence, the need for replacement. The life of the replacement battery, on the other hand, depends on how long it has been sitting on the shelf. Its shelf life is ten years in room temperature after which it goes through gradual degradation.

G Shock Strap Replacement 

G Shock watches are known to last a lifetime, but the bands wear out after prolonged use. To replace them, place the watch facing downwards on a soft cloth, unhook the spring bars located at the base of each strap. Some models have the bars covered while others are exposed. Use a spring-bar removal tool to unhook and pull the band away from the watch. Repeat the process to remove the other spring bar. Replace them with the rod slots of the new band and use the spring-bar tool to fasten the bands. The procedure applies when replacing rubber straps. Metallic bands require a little tact hence, the need to engage a professional.
