The King Seiko line of the late 1960's and 70's exude elegance and class. Packed with subtle details, and an almost gemstone like faceting of the case, one would be hard pressed to find more value in a comparably priced watch. This example from November of 1969 is, in a word, unbelievable. Proudly emblazoned beneath the Seiko logo, it has been certified as a Superior Chronometer, and the 5625 driving the hands hums along at a smooth 28,800 bph. This “Superior” classification only appears on the 56 and 45 variants of the KS line, and only during the 1969 production year. They are quite rare and difficult to obtain. The one-piece case is a classic "Tanaka" inspired design with flat polished surfaces and an array of sharp lines and contours. It is crisp and unpolished with the tightly brushed grain still intact over the lugs. On the case back, the KS medallion is complete and without blemishes. It also carries the “Superior Chronometer” designation. The dial is perfect. Unblemished in a pearlescent, silvery white sunburst with a lacquered finish, it is mesmerizing to look at. The applied markers are starkly contrasted in black, as are the atypical hands. The date can be quickset via the engraved crown, and the movement can be manually wound as well as by the rotor. We've paired it with a black distressed leather that greatly accentuates the dial, and offers exceptional comfort for everyday wear. If a rare hi-beat superior chronometer that’s remarkably well preserved is on your short list, your opportunity has arrived.
