History Introduced in 1959, the Seiko Crown was a significant step forward for the brand in terms of precision engineering and elegant design. It was developed by the Suwa Seikosha factory and featured a larger movement than its predecessors, allowing for greater accuracy, stability, and power delivery. The success and architectural layout of the Crown caliber directly paved the way for the creation of the very first Grand Seiko in 1960. As such, the Crown holds a special place in the lineage of Seiko's high-end watchmaking, embodying the refined aesthetics and mechanical ambition of the era. / Second Vintage SKU: SEI-SCJ-0019
