Spring Drive and GMT high-intensity titanium model ideal for the wrist of frequent global travelers
This model features a Spring Drive, the third movement mechanism, combining the motive force of a mainspring found in mechanical watches with the high precision of a quartz watch, as well as a GMT indicator.
This model inherits the design of the previous stainless-steel model in its rotating bezel made from sapphire crystal glass that expresses solid clarity, depth and profoundness, and the red GMT hand that stands out against the bold, black dial. The case and bracelet made from lightweight and robust high-intensity titanium, and the gold brand logo, indexes and hands are also featured to emphasize the splendor and the affluence of the watch.
The crown is placed at 4 o’clock to achieve a practical design that lets you move your wrist smoothly, even during exercise.
Thanks to the lightweight high-intensity titanium material, a comfortable fit is achieved—despite the use of a large case.
