This special model from the MT-G series, which fuses metal and resin and incorporates advanced technology, is designed with the concept of an aurora oval. A newly developed top bezel has been created by applying recrystallization and deep hardening treatments to stainless steel, and then coating it with rainbow IP. Each bezel has a unique recrystallization pattern and rainbow IP coloring, making no two alike. The case back is coated with rainbow IP on stainless steel, and the bottom surface has been repolished to expose the stainless steel again only on the raised areas—an elaborate finish. Furthermore, the band is a soft urethane band with a new purple skeleton design, paired with a rose gold IP loop and a purple IP buckle. Based on the MTG-B3000, this meticulously designed watch expresses the aurora as seen from space. 【Product】MTG-B3000PRB-1AJR Basic Information Case Size: 51.9 × 50.9 × 12.1 mm Weight: 111 g Case / Bezel Material: Carbon fiber-reinforced resin / Stainless steel Band: Resin band Water Resistance: 200 meters (20 bar) Structure & Durability Triple G Resist (Shock Resistance, Centrifugal Gravity Resistance, and Vibration Resistance) Carbon Core Guard Structure Time Adjustment & Power Source Tough Solar (solar-powered charging system) MULTIBAND6 radio-controlled timekeeping (Compatible with Japan, North America, Europe, and China) Bluetooth smartphone connectivity for automatic time adjustment Smartphone Link Features Compatible App:CASIO WATCHES Main Functions: Automatic time adjustment Easy watch settings World Time for approximately 300 cities Time & Place function Watch status display Self-check function Phone finder Exterior Features Sapphire crystal with anti-reflective coating on the inner surface Screw-lock crown Multicolor IP-coated band Deep-layer hardening treatment + IP coating Neobrite luminous coating Functions Dual Time (27 time zones with automatic daylight saving time adjustment) Stopwatch (1-second measurement, 24-hour counter, split time) Timer (Up to 24 hours) Daily alarm Super Illuminator LED light Full auto calendar Automatic hand position correction Power-saving function Battery level indicator Date and day display Power Reserve Approx. 5 months under normal use after full charge Approx. 18 months in power-saving mode Accuracy Even without radio signal reception or smartphone connection, the watch operates with standard quartz accuracy of approximately ±15 seconds per month.
