The GA-2100K-2ADR is the smoky blue variant of the nightlife-inspired GA-2100K — the coolest-toned and most futuristic of the three K-series colourways. Translucent blue resin with a matte fog finish across the bezel and band creates a hazy, atmospheric quality that evokes the blue-shifted lighting of late-night venues — laser beams cutting through smoke, neon reflecting off dark surfaces. The smoky blue case partially reveals the internal Carbon Core Guard structure through the semi-transparent material, and neon accent details provide sharp colour points against the cool haze. A newly developed smooth dial surface with piano-black gloss anchors the face.
Module 5611 is identical across all GA-2100K variants and the broader GA-2100 range: analog-digital with two hands and a day sub-dial, hand shift, world time across 31 time zones (48 cities), 1/100-second stopwatch with split time, 24-hour countdown timer, five daily alarms, double LED Super Illuminator, Neobrite lume, Carbon Core Guard, and a full auto-calendar to 2099. At 48.5 × 45.4 × 11.8 mm and 51 grams. Shock resistant, 200-metre water resistant. SR726W × 2, approximately three-year battery life.

Why You'll Love It
- The smoky blue is the most futuristic of the three GA-2100K colourways. Blue-haze translucent resin with a matte fog finish reads as cyberpunk, sci-fi, and neon-lit — it's the colour temperature of blue laser light in a dark club, or neon signs reflected in wet asphalt. Where the amber K-5A is warm and atmospheric, the blue K-2A is cool and electric. This is the nightlife variant that leans hardest into the futuristic side of the concept.
- The matte fog finish on the translucent blue bezel and band diffuses light across the surface — creating a frosted, hazy quality rather than sharp transparency. Through the smoky blue material, the Carbon Core Guard structure and internal components are partially visible, adding mechanical depth to the cool-toned exterior.
- The piano-black glossy dial provides a reflective dark centre behind the analog hands — the same newly developed smooth surface used across all three K-series variants. The deep black creates a striking contrast against the cool blue translucent bezel, with neon accent details sparking between the two like laser strobes.
- At 51 grams and 11.8 mm thin, the GA-2100K is built for extended wear — nights out, festivals, travel. No wrist fatigue, no sleeve snagging. The ultra-light resin construction with Carbon Core Guard delivers G-Shock toughness without the weight.
- Full Module 5611 functionality: hand shift, world time (48 cities), double LED Super Illuminator, five daily alarms, 1/100-second stopwatch with split time, 24-hour countdown timer. The nightlife exterior doesn't compromise the spec sheet.
- 200-metre water resistance and shock resistance. Whether it's rain at a festival, a drink spill at a club, or a bump in a crowd, the GA-2100K handles it without concern.
