THE MANUFACTORY

As one of the few fully integrated watch manufacturers in the world, Grand Seiko masters the entire process of watchmaking from the research and development of component materials to the manufacture, assembly, adjustment, inspection and dispatch.

Grand Seiko defines the essence of watchmaking in the elements of precision, beauty, readability, durability and ease of use. As the world’s leading watch manufacturer, Grand Seiko embodies precisely this essence in the outstanding quality of every Grand Seiko watch.

THE 9s CALIBER

Mechanical perfection

With 200 to 300 individual parts, mechanical watches must have an almost perfect functional consistency in the detail of their individual parts in order to ensure high precision of the movement. Seiko uses MEMS (Micro Electro Mechanical Systems) technology to bring the mechanical accuracy of the individual parts to the forefront of the technology.

However, single-part ropes alone cannot produce the precision for which Grand Seiko is known. Dhe master craftsmen, who have perfected their craft, take on the task of assembtosemping a Grand Seiko, so that they can adjust workpieces by hand to tolerances of one hundredth of a millimetre. This established craftsmanship enables the most precise precision that the 9S mechanical movement delivers.

THE 9r CALIBER

Spring Drive

Spring Drive is a unique watch technology. It generates energy like any other mechanical luxury watch, but combines it with an electronic controller to deliver a level of precision that no mechanical watch can match.

The development of Spring Drive was possible because Grand Seiko is one of the few manufacturers to master both electronic and mechanical watchmaking.

THE 9f CALIBER

Quartz on a new level

The calibre 9F redefines the quartz watch and offers higher performance and a longer service life. It is the quartz watch that deserves the name Grand Seiko. The immediate date change mechanism changes the date display in no time. The torque, comparable to that of a mechanical movement, enables the iconic wide hands of Grand Seiko. Improved second hand accuracy increases the dial’s positional accuracy compared to the markers. The sealed structure improves the retention of lubricating oils.
