A gold colored titanium oscillating weight

The oscillating weight is colored gold in honor of the 55th anniversary of the 44GS. The gold tone is achieved through a process of anodic oxidation in which the metal is subjected to electrolysis so as to generate an oxide film. Titanium oxide film produces color according to the light refraction index, enabling production of different colors by varying the thickness of the oxide film.

High precision and high functionality

Just as with 44GS, this case is designed to exemplify the precision of the hi-beat movement within. In addition, the watch offers a GMT function which allows a second time zone to be shown on the blued-steel hand. The hour can be adjusted without stopping the watch, thus preserving the high accuracy of its timekeeping.
