The engineering and design of the Seiko Crown served as the direct foundation for the first Grand Seiko model released in 1960. Powered by the manual-wind caliber 560 with 21 jewels, which was manufactured at the Suwa Seikosha factory, reference J15003 is typically attributed by specialists to the peak phase of Crown production around 1962 and 1963.
