Casio G-Shock Classic Watch GA-900AG-1AER

Introducing the Casio G-Shock GA-900AG-1AER, where G-Shock's characteristic robustness dresses in urban elegance. Its 49.5mm matte black octagonal resin case stands out with four golden screws anchoring the structure, creating an impactful visual contrast. The black textured resin strap perfectly complements the design, while the golden G-Shock logo crowns the dial with distinction.

Inside beats the Casio 5637 module, an analog-digital caliber that combines three main hands with a complete digital display. The mechanical subdials in golden tones show stopwatch and countdown functions, while the digital display at 6 o'clock presents day, date, and world time. Functions include 1/100 second stopwatch, countdown timer, five daily alarms, world time with 31 time zones, automatic calendar until 2099, and LED light for nighttime reading.

Since 1983, G-Shock has revolutionized watchmaking with its philosophy of absolute resistance. Each model passes drop tests from 10 meters, resistance to vibrations and extreme shocks. This Classic collection maintains the original essence of the Triple 10 project: resistance to 10-meter drops, 10-bar water resistance, and 10-year autonomy, adapting it to modern user demands.
