This is a special model designed with the aurora oval concept from the MT-G series, which combines metal and resin and is equipped with advanced technology. We have newly developed a top bezel made of stainless steel that has undergone recrystallization and deep hardening treatment, and is further coated with rainbow IP. The recrystallized pattern and rainbow IP coloring have different expressions, and no two are the same. The back cover is made of stainless steel and coated with Rainbow IP, and the bottom surface is re-polished to expose the stainless steel again on the convex parts, giving it an elaborate finish. In addition, the band is a soft urethane band that uses a new purple skeleton, with a rose gold IP ring and a purple IP lock. Based on the MTG-B3000, it has a carefully designed design that expresses the aurora seen from space. *Due to recrystallization of stainless steel parts processed into parts, differences in crystal grains are likely to occur, and due to this characteristic, each part has a different pattern, color tone, and gloss. *No two rainbow IP colors are the same, and each item is different. 【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.
