Casio Men's G-Shock Master of G Series Gravitymaster GR-B300-1A4JF
| Product Highlights | |
| The GR-B300 GRAVITYMASTER features a shock-resistant structure called the "Carbon Core Guard Structure," utilizing the characteristics of carbon material used in aircraft bodies (impact resistance, rigidity, and durability). By combining a case made of carbon fiber-reinforced resin with a seamless bezel inspired by next-generation aircraft, it achieves a powerful form as a GRAVITYMASTER. Designed with features like a Flight Log function for recording flight data, and Dual Time for displaying two time zones simultaneously, it captures the essence of the aviation world for aircraft and pilots. With intuitive readability in mind for crucial visibility during flights, it enhances functionality with large, three-dimensional hour markers and a metal bezel that accentuates the wide face. The use of a dual-coil motor in the 9 o'clock side's disc hand ensures precise movement and aesthetic appeal. Serving as both an alarm ON/OFF function and a stopwatch, it also functions as a battery indicator. The design incorporates high-contrast point colors reminiscent of aircraft cockpits on the dial and buttons, while offering a functional dark color variation. The case, bezel, and band are made from biomass plastic to reduce environmental impact. By ensuring time accuracy required for aviation missions through Bluetooth® connectivity for time correction and pursuing practicality with solar power, the GRAVITYMASTER supports relentless challenges towards the extreme while embodying the world of professional aviation and the "yearning for the sky." | |
