Sorry for the inconvenience.
SEIKO who sent quartz wrist watch to the world for the first time in the world continues to question the ideal image of the watch seriously and incorporates all the accumulation of technologies that can be held, quartz beyond the common sense of quartz.
Mechanical Grand Seiko's history is also a history of challenges to high precision. Even now, about half a century since the launch of the original model, in order to meet the strict accuracy standards according to the new GS standards, all the skills and skills that Seiko has cultivated are spared and continues to innovate. In 2009, a mechanical movement of 36,000 vibrations per hour (10 vibrations per second) for Grand Seiko has been newly developed in 41 years.
In the early development of the 1980s, this innovative mechanism, which was far less than a "dream" for practical use, has over 20 years of development time, overcoming many obstacles, in 2004, a mechanical watch The mechanism of coexistence which combines the complicated mechanism and taste depth, high precision of the quartz watch "spring drive automatic winding" became a fruition.
In 1969, SEIKO launched an automatic chronograph with "vertical clutch method" for power transmission for the first time in the world. In 2007, 38 years later, beyond his own history, he created the most accurate power train driven chronograph, the Spring Drive Chronograph, which uses the spring drive for the basic watch.
By specifying latitude, longitude, altitude and time with signals from 4 or more GPS satellites, it is possible to display the accurate time of the current location by simply operating wherever you go on the earth. As long as the light is hit by solar power generation, it continues to move, with power reserve display, you can understand the amount of charge at a glance.
Pioneer in the development of the wristwatch, Rolex designs, develops and produces in-house all the essential components of its watches, from the casting of the gold alloys to the machining, crafting, assembly and finishing of the movement, case, dial and bracelet.
