Casio G-Shock GA-2100AS-2A Carbon Core Guard Analog-Digital Blue Transparent Dial Men's Watch

The Casio G-Shock GA-2100AS-2A is a special edition from the Oasis of Day and Night Series, inspired by the refreshing colors of an oasis beneath the summer sun. Built on the iconic octagonal GA-2100 "CasiOak" platform, this model features a striking transparent blue dial accented with blue-green highlights, creating a vibrant design that reflects the shimmering waters of an oasis. Its slim profile and minimalist analog-digital layout make it one of the most distinctive models in the 2100 Series.

Constructed with Casio's Carbon Core Guard structure, the watch utilizes a carbon fiber-reinforced bio-based resin case for exceptional strength while maintaining a lightweight feel. Measuring 48.5 × 45.4 × 11.8mm and weighing only 51g, it offers outstanding comfort for everyday wear. A durable mineral crystal protects the dial, while 200-metre water resistance and G-SHOCK's renowned shock resistance make it suitable for sports, swimming, and outdoor adventures.

Powering the GA-2100AS-2A is Casio Module 5611, delivering ±15 seconds per month accuracy and an approximately 3-year battery life. The watch features 31 world time zones (48 cities + UTC), a 1/100-second stopwatch, 24-hour countdown timer, five daily alarms, hourly time signal, full auto calendar (to 2099), double Super Illuminator LED lighting, a hand shift function, and selectable 12/24-hour time formats.

Designed for those who appreciate bold seasonal styling without sacrificing durability, the GA-2100AS-2A combines the legendary toughness of G-SHOCK with a fresh, ocean-inspired color palette, making it one of the standout releases in the 2100 Series.
