It is a sophisticated, versatile timepiece that wears beautifully today while carrying the prestigious DNA of Seiko's most celebrated watchmaking achievements. History Launched in 1959, the Seiko Crown was a revelation in the Japanese domestic market, created to surpass the Seiko Marvel in both size and precision. The Crown's movement was larger, allowing for a bigger balance wheel and greater accuracy, which quickly established it as Seiko's premier timepiece. Its engineering and design were so successful that the Crown served as the direct base for the very first Grand Seiko in 1960. Today, the Seiko Crown is revered by collectors not just as a precursor to Grand Seiko, but as a standalone masterpiece of elegant, mid-century horology. / Second Vintage SKU: SEI-CJX-0004
