King Seiko: Seiko's Legacy of Fully Integrated Watch Manufacturing
King Seiko: The Pride of Japanese Horology
Seiko stands as one of the few fully integrated watch manufactures in the world, designing and developing their own movements using leading-edge technology. The King Seiko collection represents this manufacturing excellence, showcasing the company's ability to create timepieces entirely in-house from movement to case.
The Heritage of King Seiko
King Seiko was originally introduced in 1961 as a competitor to Grand Seiko, representing the highest level of mechanical watchmaking at Seiko's Daini factory. The collection was designed to offer exceptional accuracy and finishing at a more accessible price point than its Grand Seiko sibling.
After being discontinued in 1975, King Seiko was revived in 2020 to celebrate Seiko's manufacturing heritage and meet growing demand for heritage-inspired timepieces. The modern King Seiko pays homage to the original while incorporating contemporary technology and design elements.
