G-Shock GBM2100A-8B G-Steel

Building on the foundation of its original 1983 release, G-SHOCK continues to push boundaries in its pursuit of uncompromising toughness. The latest addition to the 2100 series preserves the collection’s signature slim profile while enhancing functionality with Smartphone Link connectivity and Tough Solar power—all housed within a refined metal-bezel design. The case and band feature select components made from bio-based resin, a more sustainable material that helps reduce environmental impact. The GBM-2100A-8B stands out with a light yellow-gold vapor-deposited dial accented by sleek black vapor-deposited hour markers, creating a modern and stylish finish. - Module No. 5729 - 49.3 x 44.4 x 11.9mm Case Size - 72g Weight - Shock resistant (G-SHOCK) - Tough Solar (Solar powered) - Double LED light - Mobile link (Wireless linking using Bluetooth®) - Hand shift feature (Hands move out of the way to provide an unobstructed view of digital display contents) - World time: 38 time zones (38 cities + coordinated universal time), auto summer time (DST) switching, home city/world time city swapping, city code display, city name display, daylight saving on/off - 1/100-second stopwatch - Countdown timer - 5 daily alarms - Hourly time signal - Battery level indicator - Power Saving (display goes blank to save power when the watch is left in the dark) - Full auto-calendar (to year 2099) - 12/24-hour format - Button operation tone on/off - Date/month display swapping - Day display (days of the week selectable in six languages) - Regular timekeeping *Analog: 2 hands (hour, minute (hand moves every 20 seconds)), 1 dial (mode, battery level) *Digital: Hour, minute, second, pm, month, date, day - Accuracy: ±15 seconds per month (with no mobile link function) - Approx. battery operating time: 7 months on rechargeable battery (operation period with normal use without exposure to light after charge) *18 months on rechargeable battery (operation period when stored in total darkness with the power save function on after full charge)
