Basel 2014 - Grand Seiko - Hi-beat GMT

 grand seiko

Introducing the new Hi-beat 36,000 GMT 

Seiko Watch Corporation is pleased to announce the global launch of a new caliber, its first ever hi-beat GMT. Caliber 9S86 has been created on the platform of the hi-beat caliber 9S85 that, since 2009, has been the leading watch in the Grand Seiko collection. It has all the features of the existing caliber, with the addition of a 24-hour GMT hand with easy hour adjustment.

HI-BEAT 36,000 GMTLeading the creation for 2014 is the Hi-beat 36,000 GMT Limited Edition, designed especially to celebrate the launch of the new caliber. In both performance and appearance, it expresses the very best of Seiko’s mechanical watchmaking and raises traditional watchmaking to the level of art. The caliber has a high accuracy of +5 to -3 seconds a day and a power reserve of 55 hours. The GMT hand can be used as a dual time indicator with the hour hand being adjustable independently as the time of day hands continue to mark time. It is the perfect watch for the international traveler.

The case is based on the highly acclaimed 44GS design that was shown at Baselworld 2013. It is a contemporary reinterpretation of this iconic Grand Seiko design and offers highly polished, distortion-free surfaces and perfect comfort on the wrist. The beauty of the dial complements the simplicity of the case. It has a delicate and beautiful radial pattern that is inspired by the many ridged contours of Mt. Iwate, the mountain that is visible through the wide windows of the Shizukuishi Watch Studio where all Grand Seiko mechanical watches are designed, manufactured and assembled, by hand, by the studio’s craftsmen and women. The natural beauty of the studio’s location high up in the hills of Northern Japan near Morioka is both a source of inspiration and pride for the Grand Seiko watchmakers. Through the sapphire case-back glitters a specially designed titanium oscillating weight. The upper part of the oscillating weight is treated with an anodic oxidation* of the titanium to deliver a special gold tone.  Anodic oxidation treatment involves the surface materials subjected to electrolysis, to artificially generate oxide film. Titanium oxide film produces color according to the light infraction index, enabling production of different colors by varying the thickness of the oxide film. Titanium is also used for its high elasticity and vibration absorbency, which reduces distortion of the oscillating weight and impact on the weight bearings. The titanium oscillating weight carries the Grand Seiko emblem in the Limited Edition Hi-beat SBGJ005 and is available in just 600 pieces.

Two additional 9S86 creations are also being released at Baselworld 2014, one with a white dial (SBGJ001)and one with black (SBGJ003). The case is identical in all three variations.

Thanks to its rapidly increasing success in Japan and its growing presence in Europe and other markets, the Grand Seiko collection is expanding in 2014. Diverse though the new additions may be, they all express anew the simple yet powerful philosophy of Grand Seiko. Every Grand Seiko watch showcases the pure essentials of watchmaking, with craftsmanship and high technology manufacturing being harmonized to create watches that are as accurate, as legible, as comfortable and as durable as can be achieved.
