Casio G-shock Men Quartz Black Dial Analog-Digital Resin Watch G1785

The CasiOak. Reinvented for the Nightlife.

Immerse yourself in the feel of mysterious, smoky light with a watch inspired by the music-driven nightlife. The GA-2100K-2A brings to life the shadowy thrill of nightclubs and music festivals, with laser strobes cutting through the beat of midnight music captured in watch form.

A Newly Developed Surface Finish

A newly developed surface finish imparts a clean look to the dial that perfectly complements the streamlined design of GA-2100 watches. This smooth surface is the ideal canvas for the glossy finish and rich colour scheme used across the K Series.

Nightlife-Inspired Translucent Texture

The varying textures and colours of the watch components recall the late-night music scene. Translucent materials with a matte finish are employed to give the bezel and band a fantastic texture reminiscent of the dance floor haze created by a fog machine, while accents sparkle like laser light cutting through the dark.

The Iconic CasiOak Octagonal Design

Part of the legendary GA-2100 series, nicknamed "CasiOak" by fans for its resemblance to luxury sports watches, this model borrows its bezel and band shape from the classic DW-5000 origin model, blending analog elegance with G-Shock's digital functionality.

Carbon Core Guard for Slim Toughness

Built with Carbon Core Guard structure using highly rigid fine resin containing carbon fibre, this watch achieves a remarkably slim 11.8mm thickness while maintaining full G-Shock shock resistance.

Comprehensive Digital Functionality

Equipped with a hand shift feature, world time covering 48 cities, a 1/100-second stopwatch, a countdown timer, and 5 daily alarms, this watch packs serious functionality into its slim analog-digital hybrid display.

Double LED Light for Visibility

Featuring a Double LED light (Super Illuminator), this watch ensures clear visibility of both analog hands and digital display in any lighting condition, day or night.

20 Bar Water Resistance

Rated for 20 bar (200m) water resistance, this watch is built to handle everyday exposure to water, rain, and splashes without compromise.
