Introducing the G-SHOCK as nature-minded as you, made with renewable materials and a focus on sustainability. Its base in the GAB2100, which comes with handy functions like Smartphone Link and Tough Solar charging while maintaining the distinctive octagonal form of the GA2100. Then, the key resin components are made with bio-based resin produced from renewable organic resources, which are expected to help curb CO2 emissions and reduce environmental impact. Focus on nature is taken to the next level with very special cloth bands that feature the work of two innovators — TRUECOTTON and FOOD TEXTILE — to reduce waste and promote ethical sourcing. The cloth for the bands is made of traceable organic TRUECOTTON so we know which farm and spinning mill it comes from. This not only helps manage environmental impact, but also ensures workers are protected and craftsmanship is high quality throughout the production process. The bands are colored with dyes from FOOD TEXTILE, a project to reuse food that would otherwise be discarded to create natural dyes. Soft, earthy colors are brought to life with dyes made with over 90% natural ingredients. The dark brown hue of the GAB2100CT-1A5 band is achieved with a dye extracted from coffee, while the khaki grey color of the GAB2100CT-5A band comes from a dye extracted from echinacea. Materials that had been destined for the trash are reborn in a beautiful new form — a sustainable, environmentally friendly watch. <ul><li>Case/bezel material: Carbon / Bio-based resin</li><li>Dark Brown Cloth band (Made of traceable organic TRUECOTTON)</li><li>Mineral Glass</li><li>Shock Resistant</li><li>Carbon Core Guard Structure</li><li>Tough Solar (Solar powered)</li><li>200-meter water resistance</li><li>Mobile link (Wireless linking using Bluetooth®)</li><li>World time:38 time zones (38 cities + coordinated universal time), city code display, city name display, daylight saving on/off, auto summer time (DST) switching, Home city/World time city swapping</li><li>1/100-second stopwatch</li><li>Countdown timer</li><li>5 daily alarms (with 1 snooze alarm)</li><li>Hourly time signal</li><li>Double LED light</li><li>LED light for the face (Super illuminator, selectable illumination duration (1.5 seconds or 3 seconds), afterglow)</li><li>LED backlight for the digital display (Super illuminator, selectable illumination duration (1.5 seconds or 3 seconds), afterglow)</li><li>Full auto-calendar (to year 2099)</li><li>Mute feature: Button operation tone on/off</li><li>12/24-hour format</li><li>Date/month display swapping</li><li>Day display (days of the week selectable in six languages)</li><li>Hand shift feature (Hands move out of the way to provide an unobstructed view of digital display contents.)</li><li>Regular timekeeping: Analog: 2 hands (hour, minute (hand moves every 20 seconds)), 1 dial (battery level, mode); Digital: Hour, minute, second, pm, month, date, day</li> <li>Size of case: 48.5 × 45.4 × 11.9 mm</li><li>Casio G-Shock Style #: GAB2100CT-1A5</li></ul>
