Have Mt Iwate on Your Wrist with this Hi-Beat Model

This model incorporates Caliber 9S86, the high-specification movement that delivers the same accuracy (-5 to +3 seconds a day) and the same power reserve (55 hours) as the core Caliber 9S85, while also offering the GMT function that the international traveler needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed.

The GMT hand shows the time in the home time zone. 

The exterior design is a modern take on the stunning Grand Seiko Style - the embodiment of the Grand Seiko design philosophy which was first established for the 44GS in 1967 - and features a distortion-free, wide mirror surface throughout. 

A beautifully delicate and polished finish has been created on the dial, with a Mount Iwate pattern, inspired by the many-ridged contours of the Mt. Iwate, the mountain that is visible through the windows of the Shizuku-Ishi Watch Studio where Grand Seiko mechanical watches are made.

About Grand Seiko

Grand Seiko was established in 1960 with the mission to create "ideal" watches with standards of precision, durability and beauty that would lead the world. Grand Seiko watches are a reflection of Japanese aesthetics and are notable for the purity, simplicity and subtlety of their designs. Grand Seiko calls it “functional beauty,” a style that does not interfere with the reading of the time, but enhances it with harmonious case lines and uncluttered, easy-to-read dials. Key to the design are polished surfaces that reflect rays of light. Since ancient times, Japanese people have admired the subtle gradations between light and shadow in nature. With that inspiration, Grand Seiko uses a simple case design composed of a flat plane and curved line that respond to the movement of light. Grand Seiko creates this hard-edged, flat-surfaced case through a process called Zaratsu, giving the case a mirror-like smoothness where light and shadow play.

Grand Seiko makes watches with three different kinds of movements: mechanical, quartz, and Spring Drive. Spring Drive is a technical breakthrough invented by Seiko that combines the best of mechanical and quartz technologies. It’s an automatic watch that gives quartz accuracy without using a battery. No other watch company has this technology. It is a testament to the watchmaking savvy of a firm that has made mechanical watches since 1895.
