This watch wont let you down

Whether you are on shift, travelling or training, the G-SHOCK GA-2000S-1A is built to deliver durability, comfort and everyday functionality in one rugged package.

Built for everyday toughness
The Carbon Core Guard structure combines carbon and resin materials to improve shock resistance while keeping the watch lightweight and comfortable on the wrist. Designed to handle knocks, impacts and demanding environments, the GA-2000S-1A is built for daily wear without feeling bulky.

Lightweight and comfortable
At just 64g, the compact design stays comfortable during long shifts, training sessions and everyday use. The flexible resin band provides a secure fit while the rugged case design maintains the tough G-SHOCK look.

Ready for low-light conditions
Double LED Super Illuminator lighting keeps both the analogue dial and digital display visible in darker environments. Whether checking the time during night shifts or early morning training, visibility stays clear when you need it most.

Practical features for daily use
World time across 31 time zones, five daily alarms, a countdown timer and a stopwatch give you the tools needed for work, travel and training. The hand shift feature temporarily moves the hands away from the digital display for a clearer view of important information.

Designed around function
The large front light button, bold analogue-digital layout and rugged carbon-inspired design give the GA-2000S-1A a clean, professional look while maintaining the durability G-SHOCK is known for. Interchangeable band compatibility also allows you to customise the watch to suit your setup or style.
