Features:

Seamless Design Offering Functional Beauty

The seamless exterior design is inspired by the organic form of next-generation aircraft. A sense of unity is achieved by smoothly connecting the exterior surfaces from the case to the band. This design creates a tough, cutting-edge look, perfect for the new addition to the GRAVITYMASTER line.

Enhanced Readability with 3D Face Design

The large-diameter, triple-layer dial, designed with a sense of depth, ensures readability for pilots who require intuitive time reading. Featuring large, dimensional index marks and inset dials inspired by instrument panels, the metal bezel accentuates the watch face, combining functionality with striking design.

Dual Time: Simultaneous Display of Time in Two Cities

The main dial and inset dial show times in two different cities simultaneously, making it easy to manage multiple time zones. With a dedicated app, configuring world time settings is effortless. Switching between home time and world time is also a breeze. This watch ensures accurate time management is just a fingertip away.

Coloration Evoking the Look of a Cockpit

A high-contrast black-and-white color scheme enhances the visibility of the watch hands and index marks, ensuring the most vital functions are clear. Red and blue color variations are also available, with the red model inspired by the nighttime illumination of a cockpit instrument panel and the blue by a head-up display (HUD). These distinctive color combinations deliver practical functionality while expressing an aviation-inspired worldview.

Details:

Layer Guard and Carbon Core Guard structures: Innovatively combining materials

The intricately shaped bezel features integrated molding with two rings—a metal ring and a urethane ring—positioned beneath it. This unique material combination enhances the bezel's visual appeal, embodying the complexity and sophistication seen in next-generation aircraft design. The case is crafted from carbon fiber-reinforced resin, balancing strength with lightweight properties. Inspired by hazard warning stripe tapes, the side buttons are textured for anti-slip functionality. Additionally, operational efficiency is improved by eliminating guards beneath the buttons.

Rotary Disc Indicator: Multi-Function Display

Located at the 9 o'clock position, the rotary disc indicator employs a dual-coil motor for seamless rotation. It provides clear indications for battery levels, alarm status (on/off), and dynamic motion linked to each operational mode.

Flight Log: Streamline Your Flight History Management

Synchronize your watch with a smartphone and effortlessly record the current time and location on a map using a dedicated app. This feature is invaluable for maintaining detailed flight logs, and capturing precise departure and arrival times, and locations. Furthermore, organize and manage your travel records efficiently by grouping plotted data, encompassing departure points, transit locations, and final destinations.

Attention to Materials: Bio-Based Resin

The key resin components used in the case, bezel, and band are crafted from bio-based resin. Derived from renewable organic resources, this material is designed to minimize environmental impact, offering a sustainable choice.

Solar-powered timekeeping with Bluetooth® for enhanced accuracy and reliability

Super Illuminator (high-brightness LED light) for maintaining watch readability in the dark
