The black dial, with its rough texture reminiscent of raw titanium, features three metal rings laid out as the inset dial. This is combined with a face ring with a rough metallic texture to create a powerful and masculine look.

　This watch is equipped with the world's fastest Eco-Drive GPS satellite-wave movement, Cal. F950, which receives time information only in as little as three seconds, and displays the time by rapidly adjusting the home time hour and minute hands.

　This is the first model to use "Duratect MRK+DLC," a coating made by layering "Duratect MRK," which hardens the surface of the material, on top of which "Duratect DLC," which is coated on the surface using low-temperature plasma technology. It is resistant to not only scratches but also dents. It is also metal allergy resistant.

2018: Birth of a 3.53mm thin model using Super Titanium™
