The case and band's main resin parts use biomass plastic for a more environmentally conscious build. The dial gets a vapor-deposited blue finish with silver vapor-deposited indices for a design that moves easily from casual to business settings. The stainless steel bezel and glass-fiber-reinforced resin inner case protect the module, with the iconic octagonal bezel shaped through forging, cutting, and polishing — circular hairline finished on top, mirror polished on the sides.\u003c\/p\u003e\n\n\u003cp\u003eBluetooth connects to the CASIO WATCHES app for automatic time correction, world time for approximately 300 cities, Time \u0026amp; Place location logging, reminders, and phone finder, all backed by stable Tough Solar power and a double LED light for after-dark visibility.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eGBM-2100A-2BJF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eG-SHOCK ANALOG-DIGITAL \/ 2100 Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase size\u003c\/td\u003e\n\u003ctd\u003e49.3 × 44.4 × 11.9 mm \/ 1.94 × 1.75 × 0.47 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e72 g \/ 2.5 oz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase \/ bezel material\u003c\/td\u003e\n\u003ctd\u003eResin (biomass plastic) \/ stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBand\u003c\/td\u003e\n\u003ctd\u003eResin band (biomass plastic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGlass\u003c\/td\u003e\n\u003ctd\u003eMineral glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater resistance\u003c\/td\u003e\n\u003ctd\u003e20-bar (200-meter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStructure\u003c\/td\u003e\n\u003ctd\u003eShock resistant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTime correction\u003c\/td\u003e\n\u003ctd\u003eBluetooth (auto time correction via smartphone)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower source\u003c\/td\u003e\n\u003ctd\u003eTough Solar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther\u003c\/td\u003e\n\u003ctd\u003eNeobrite luminous material\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMobile Link \/ App\u003c\/td\u003e\n\u003ctd\u003eCASIO WATCHES app — auto time correction, easy watch setting, world time (approx. 300 cities), Time \u0026amp; Place, reminders, phone finder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctions\u003c\/td\u003e\n\u003ctd\u003eWorld time (38 cities \/ 38 time zones + UTC, auto DST, home city swap), Stopwatch (1\/100-sec under 1 hr, 1-sec over 1 hr, 24-hr, lap\/split), Timer (1-sec unit, max 60 min), 5 daily alarms + hourly time signal, Double LED light (dial + LCD backlight, Super Illuminator with afterglow, switchable duration), Full auto calendar, Operation sound on\/off, Power saving function, Battery indicator, Hand retreat function, 12\/24-hour format, Date display (month\/day swap), Day-of-week display (6 languages)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery life\u003c\/td\u003e\n\u003ctd\u003e~7 months (with functions) \/ ~18 months (power saving)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003eAverage monthly deviation ±15 seconds (standard quartz accuracy when Bluetooth sync unavailable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBand size\u003c\/td\u003e\n\u003ctd\u003e145–215 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelease date\u003c\/td\u003e\n\u003ctd\u003eAugust 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n","brand":"Japan Treasure Factory","offers":[{"title":"Default Title","offer_id":58366203134255,"sku":"GBM-2100A-2BJF","price":298.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9679\/1343\/files\/GBM-2100A-2BJF-01.avif?v=1787659580","url":"https:\/\/jtfwatches.com\/products\/casio-g-shock-gbm-2100a-2bjf-blue-dial-metal-bezel-bluetooth-tough-solar","provider":"Japan Treasure Factory","version":"1.0","type":"link"}
