Welcome the MRG-B5000, based on the first-ever G-SHOCK and crafted with the state-of-the-art metals and meticulous finishes that are the hallmark of the MR-G flagship line. These breakthrough timepieces are a study in metal craftsmanship. The case and bezel are made of Ti64-based super-hard titanium alloy, while the band is made of another special titanium alloy, DAT55G, that is both three times harder than pure titanium and highly workable. The bezel top is crafted in COBARION®, a cobalt-chrome alloy four times harder than pure titanium. The bezel alone consists of 25 different components, each individually polished for a stunning detailed texture. The state-of-the-art Multi-guard Structure incorporates flat springs and silicone buffers to the multi-component bezel, ensuring outstanding shock absorption to protect the dedicated MR-G module with gold-plated retainer plate. MRG-B5000B has its polished sheen and diamond-like carbon coating for the same brilliant black as the very first G-SHOCK it takes after, but in a lustrous mirror finish. The watch face features an iconic brick pattern and red line in a nod to the original design. These metallic beauties deliver when it comes to function, too, with radio-controlled calibration and smartphone pairing via Bluetooth®. 49.4x43.2x12.9mmShock ResistantScrew Lock BackSapphire crystal with glare-resistant coatingDiamond Like Coating200-meter water resistanceCase / bezel material: Titanium / CobarionSolid titanium band with tight-lock, 1-press, 3-fold claspTough Solar (Solar powered)LED backlight (Super illuminator): Full auto LED light, selectable illumination duration (2 seconds or 4 seconds), afterglowTime calibration signal receptionMobile link (Wireless linking using Bluetooth®)>5 World time: 39 time zones (39 cities +coordinated universal time), daylight saving on/off, Home city/World time city swapping, auto summer time (DST) switching1/100-second stopwatchCountdown timer5 daily alarms (with 1 snooze alarm)Hourly time signalLow battery alertPower Saving (display goes blank to save power when the watch is left in the dark)Full auto-calendar (to year 2099)12/24-hour formatButton operation tone on/offDate/month display swappingDay display (days of the week selectable in six languages)Regular timekeeping: Hour, minute, second, pm, month, date, dayAccuracy: ±15 seconds per month (with no signal calibration and mobile link function)Approx. battery operating time: 10 months on rechargeable battery (operation period with normal use without exposure to light after charge) and 22 months on rechargeable battery (operation period when stored in total darkness with the power save function on after full charge)Casio G-Shock Style#: MRGB5000B-1...
