The 1964 Crown Chronograph was Seiko’s, and Japan’s, first chronograph watch. Every aspect of the watch was designed from scratch and it marked the beginning of Seiko’s chronograph wrist watch manufacturing. It had a simple one-push mechanism but it amply demonstrated the same commitment to precision as would Caliber 6139 and all its successors with the inclusion of a column wheel to control the start, stop and reset functions.
The new chronograph is faithful to the design of the 1964 Crown Chronograph with its box-shaped crystal, its sharply defined numerals on the narrow bezel and the inwardly tilted case shape that allows the watch to sit tight on the wrist.
Of course, every detail is upgraded; the movement is the 8R48 with its 12 hour chronograph and 45 hour power reserve, the crystal is sapphire with anti-reflection coating on the inner surface and the lugs are Zaratsu polished.
The new Presage limited edition watch that commemorates this 1964 landmark uses Seiko’s most advanced chronograph caliber, 8R48, which was first created in 2014. In addition to the vertical clutch and column wheel, it incorporates Seiko’s unique three-pointed hammer and a heart-shaped cam which ensure the perfect synchronization of the hands’ fly-back. The watch is presented in the Presage collection as a limited edition of 1,000.
