History Introduced in the early 1960s, the Seikomatic line was a cornerstone in Seiko's strategy to popularize automatic watches. By recessing the crown at the 4 o'clock position, Seiko sent a clear message to consumers: the automatic winding system was so efficient that manual winding was no longer necessary. These watches laid the mechanical and aesthetic groundwork for the high-end automatic King Seiko and Grand Seiko models that would soon follow, cementing the Seikomatic's place as a deeply important chapter in Seiko's rich history.
