Grand Seiko Sport SBGN005
The First Grand Seiko 9F Quartz GMT Model
Perfect for the world traveller.
Caliber 9F, which was developed to create the ultimate quartz watch, now features the GMT function for the first time.
This new addition to the Grand Seiko Sport Collection allows you to fully enjoy the newly-designed Caliber9F86 in a genuinely sporty design with the sophisticated thinness (12.1mm) that is unique to quartz watches.
The watch allows you to move the hands without stopping the watch when setting it to local time. This achieves a convenience in which excellent accuracy of the quartz watch won’t be lost.
The case features a simple three-dimensional, thin design, which creates a comfortable fit. By featuring a screw-lock crown, the watch maintains excellent airtightness and water resistance as well as durability.
The contrast created by the striking GMT hand and the upper and lower two-toned dial rings helps you intuitively tell whether the time indicated by the GMT hand is day or night.
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.
