It features a shock-resistant structure called the \"Carbon Core Guard Structure,\" incorporating carbon fiber-reinforced resin in the case and a seamless bezel inspired by next-generation aircraft, creating a powerful form befitting the GRAVITYMASTER series. Designed for flight recording, it offers features like a flight log function for recording current position and time, and a dual time display for showing two time zones simultaneously, enhancing the aviation world for pilots and aircraft alike. With intuitive readability essential for flight situations, it boasts large, three-dimensional hour markers and a metal bezel that accentuates the wide face, enhancing functionality. The use of a dual-coil motor in the 9 o'clock side's disk hand ensures precise movement and aesthetic appeal. In addition to functions like alarm ON\/OFF and stopwatch, it serves as a battery indicator. The design combines high-contrast point colors seen in aircraft cockpits with functional dark color variations on the case, bezel, and band. Environmentally friendly biomass plastic is used in the case, bezel, and band. By incorporating Bluetooth® connectivity for time correction, it ensures the time accuracy required for aviation missions while also prioritizing practicality with solar power. The GRAVITYMASTER supports relentless challenges toward the limits, embodying the world of professional aviation and the aspiration for the skies.\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\" style=\"font-weight:800; padding:5px;background:#d9d9d9;\"\u003eProduct
