Engineered with meticulous attention to detail, the dial features a refined surface finish that complements the GA-2100's iconic clean lines. A lustrous piano-black colour palette and high-gloss sheen create an understated elegance, while neon accents punctuate the design like flashes of light cutting through darkness. The matte, translucent bezel and band deliver tactile contrast, evoking the sensory experience of smoke and haze on a crowded dance floor. Layered textures and tones work in harmony, capturing the essence of the contemporary music scene. Built on G-SHOCK's legendary durability, this timepiece merges forward-thinking aesthetics with uncompromising toughness—a watch that thrives in any environment, from festival grounds to everyday wear. **We are a Casio UK authorised dealer** **New boxed stock with full retail boxes & paperwork** **Basic Information** Case size (L× W× H) 48.5 × 45.4 × 11.8 mm Weight 51 g Case and bezel material Carbon / Resin　 **Band** Resin Band Construction Shock Resistant Carbon Core Guard structure Water resistance 200-metre water resistance Power supply and battery life Approx. battery life: 3 years on SR726W X 2 Country of origin Thailand **Exterior** Glass Mineral Glass Compatible band size 145 to 215 mm Other Neobrite **Watch Features** World time 31 time zones (48 cities + Coordinated Universal Time), daylight saving on/off Stopwatch 1/100-second stopwatch Measuring capacity: 00'00''00 to 59'59''99 (for the first 60 minutes) 1:00'00 to 23:59'59 (after 60 minutes) Measuring unit: 1/100 second (for the first 60 minutes) 1 second (after 60 minutes) Measuring modes: Elapsed time, split time, 1st-2nd place times Timer Countdown timer Measuring unit: 1 second Countdown range: 24 hours Countdown start time setting range: 1 second to 24 hours (1-second increments, 1-minute increments and 1-hour increments) Alarm/hourly time signal 5 daily alarms Hourly time signal Light Double LED light LED light for the face (Super illuminator, selectable illumination duration (1.5 seconds or 3 seconds), afterglow) LED backlight for the digital display (Super illuminator, selectable illumination duration (1.5 seconds or 3 seconds), afterglow) Light colour LED: White Calendar Full auto-calendar (to year 2099) Mute feature Button operation tone on/off Accuracy Accuracy: ±15 seconds per month **Other features** 12/24-hour format Hand shift feature (Hands move out of the way to provide an unobstructed view of digital display contents.)
