Oakley says: We took the best of the digital world, gave it an analog face and a steel backbone, then let it roam 24 time zones. The Oakley GMT wristwatch combines the precision of quartz calibration with an intuitive design that navigates time around the globe. A simple adjustment of the World City hand is all that’s needed for local time to display automatically. Dual alarm modes are set with the ease of specialized controls and a dedicated alarm dial face. A pure sapphire crystal is treated with anti-reflective coating and sealed over the high-contrast display. Durability is enhanced by a design that withstands pressure equivalent to 330 feet (100 meters) beneath the surface. Engineered with the ergonomics of a spinal column, the highest grade of surgical stainless steel is crafted into stout links of solid metal. The digitally rendered geometry curls around your wrist for maximized comfort and fit.
