Casio G-Shock GA-2100GB-1A Carbon Core Guard Analog-Digital Gold Dial Men's Watch

The Casio G-Shock GA-2100GB-1A combines the iconic octagonal design of the 2100 Series with a premium metallic finish. Popularly known as the "CasiOak", this model features a striking gold metallic dial with a gold vapor-deposited finish and matching gold-tone index markers. The dial is enhanced with a circular hairline texture, creating a sophisticated contrast against the minimalist analog-digital display while maintaining the legendary toughness of G-SHOCK.

Built with Casio's Carbon Core Guard construction, the watch utilizes a carbon fiber-reinforced resin case that offers exceptional durability while remaining lightweight. Measuring 48.5 × 45.4 × 11.8mm and weighing just 51g, it is one of the slimmest G-SHOCK models. A durable mineral crystal protects the dial, while 200-metre water resistance and G-SHOCK's renowned shock-resistant construction make it ideal for everyday wear, sports, and outdoor adventures.

The GA-2100GB-1A is powered by Casio Module 5611, delivering ±15 seconds per month accuracy and an approximately 3-year battery life. It features World Time (31 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.

The GA-2100GB-1A belongs to Casio's Gold & Silver Color Series, combining a luxurious metallic gold dial with the slim octagonal case that has made the GA-2100 collection one of G-SHOCK's most successful modern designs. It is an excellent choice for those seeking a bold yet versatile everyday timepiece.
