A clear domed acrylic crystal protects the dial, showing no major scratches or cracks.

Its beautifully aged 14K gold-filled case and historically significant 23-jewel manual-winding movement make it a compelling and charismatic addition to any vintage collection. History The Seiko Cronos was introduced in 1958 by the Daini Seikosha factory as a direct internal competitor to the Suwa factory's highly successful Marvel line. Produced around 1959, the reference J14021 represents a pivotal era of rapid advancement and internal rivalry within Seiko. The manual-winding movement used in the Cronos, known as the Caliber 54, proved so reliable and well-engineered that it ultimately served as the foundational base for the very first King Seiko, cementing the model's lasting legacy in Japanese watchmaking history. / Second Vintage SKU: SEI-CDJ-0007
