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.
