Experience the thrill of exploration with this timepiece that screams toughness, durability, and a strong sense of adventure. Designed with the spirit of overlanding in mind, this watch combines a rugged aesthetic, reminiscent of offroad vehicles and survival gear, with the practicality of a chronograph.

Outstanding Design and Structure

  • Innovative Guard Structure: This watch features an innovative guard structure, combining different materials like stainless steel for the bezel ring, guards, and front button guard, and carbon fibre-reinforced resin for the side button guards. A diamond-like carbon (DLC) coating is applied to these surfaces, providing enhanced abrasion resistance.
  • Dust, Mud, and Vibration Resistance: Equipped with stainless-steel protected buttons, gasket fitted button shafts, and a screw-lock crown, this timepiece is designed to resist dust, mud, and vibrations.

Advanced Sensor Features

  • Triple Sensor: Stay ahead of the changing conditions with a pair of compasses, an altimeter/barometer, and a thermometer. You can even check the direction to a desired destination with the second hand indicating north and the indicator hand showing the recorded direction.
  • Digital Compass: This watch includes a 60-second continuous direction measurement and auto horizontal compensation.
  • Thermometer: Measure the temperature at your current location with the built-in thermometer.
  • Barometer & Altimeter: Stay informed with sudden atmospheric pressure changes and measure altitude in a one-second interval.

Material and Technology

  • Carbon Core Guard Structure: The carbon fibre-reinforced resin case protects the module, ensuring high strength and durability.
  • Bio-based Resin: Key resin components are made with bio-based resins, produced using renewable organic resources, reducing environmental impact.
  • Solar-Powered Timekeeping: Enhanced accuracy and reliability with Bluetooth® and radio control.
  • Super Illuminator: High brightness full-auto double LED light ensures readability in the dark.
  • Sapphire Crystal: The watch features a scratch-resistant, highly transparent sapphire crystal with an anti-reflective coating.
