This watch celebrates the 55th anniversary of 44GS's first launch in 1967. The 1967 44GS was the watch that first embodied the design code known as the ‘Grand Seiko Style’ which gave Grand Seiko its distinctive look and which inspires every new creation to this day. Its international recognition was enhanced when the 44GS Hi-Beat 36000 GMT won an award at the 2014 Grand Prix d'Horlogerie de Genève. This watch shares the same design as the 55th Anniversary Limited Edition but the case and bracelet are in high-intensity titanium, a material that is 30% lighter than steel and highly resistant to both scratches and corrosion.
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.
