The distinct "Seiko Crown" script logo is applied at the 12 o'clock position, while the "Diashock 19 Jewels" text is printed crisply above the 6 o'clock mark. The peripheral minute track remains intact and legible. Case and Crystal The stainless steel case measures 35mm in diameter and retains strong, defined lines on the lugs and bezel. There are signs of light vintage wear and handling marks consistent with age, but no major dings or deep scratches that detract from the overall aesthetic. The snap-back caseback features the correct engravings, including the Seiko Crown signature and the reference number J15011, which remain legible. The acrylic crystal is clear and domed, enhancing the vintage character of the dial. Movement Powering this timepiece is the manual winding Seikosha Caliber 560, a 19-jewel movement renowned for its reliability and historical significance. The movement bridges appear clean and free of oxidation. Timegrapher testing displays a rate of -58s to -63s/day, which indicates a complete and running movement offering vintage performance. Strap The watch is fitted with a black leather strap featuring contrasting gold-tone stitching that complements the gold indices on the dial. The strap is in good condition, soft and pliable, and is secured by a silver-tone pin buckle that suits the stainless steel case. Condition This example is in excellent vintage condition. The most striking feature is the preservation of the dial, which is free from the heavy spotting or patina often found on models of this era. The case edges are well-preserved, and the caseback engravings are visible. The movement winds and sets smoothly, offering an authentic vintage ownership experience. Dimensions The case diameter is 35mm excluding the crown. The lug-to-lug length ensures a comfortable fit on a variety of wrist sizes, adhering to the classic dress watch proportions of the 1960s. Remarks The Seiko Crown is often cited by collectors as one of the best value propositions in vintage watch collecting due to its direct lineage to the Grand Seiko. This specific example, with its mix of a stainless steel case and gold-tone dial furniture, offers a versatile look suitable for both formal and casual wear. History Introduced in 1959, the Seiko Crown was a significant technical leap forward for the company, replacing the Marvel as the flagship precision wristwatch. It utilized a larger movement diameter to accommodate a larger balance wheel, which improved isochronism and accuracy. The success of the Crown directly paved the way for the release of the first Grand Seiko in 1960, making the Crown an essential piece for any serious collector of Japanese watches. / Second Vintage SKU: SEIBOHJ1I0000
