All dynasties begin somewhere, and in 1961 the “Tsunami” logo was etched into a case back for the very first time. A two piece screw down case back to be exact, and it was fitted onto Seiko’s very first foray into dive watch territory. The Silver Wave was rated to 50m, and though it hardly resembles a modern dive watch, its importance to the brand can’t be overstated. It is the foundation on which generations of diver innovations and milestones have been built. The J12082 was only produced for about three years in the 50m variant, and was followed in 1964 by a more economical, and relatively much more common 30m version. If you’ve had the opportunity for an “in hand” comparison of both, the difference in build quality is less than subtle. This very early example from August of 1963 is spectacular, and marks only the second like it we’ve ever brought to market. The silvery white sunburst dial bears the eight pointed star logo, and “SD” insignia meant to denote Seiko’s “Special Dial” treatment. This which included intricate finishes and precious metal (14kt/18kt gold) markers. Setting this dial apart is the cross finish “snow flake” or “star burst” pattern that radiates outward to the markers from the center. In addition, the printing variates from the standard model by foregoing the “50m” line, and moving the “Diashock 20 Jewels” line from the 12 side to the 6. The original luminous plots are intact, and set just inside of each polished white gold marker along the tips of the snow flake. Each has developed an even khaki patina. The dial transitions lacquered black inner bezel via a beveled minute chapter, and well proportioned “count up” printing. Zero is marked with a large white crest, and luminous triangle. It can be rotated via the crown in either direction. The hour and minute hands are are sharply tapered dauphines, and have retained their polished finish, and the luminous windows share the same warm patina as the hour markers. The long and slender sweep counting the seconds reaches well into the subtle minute hashes framing the dial. The case is unpolished with sharp corners and bevels, but the “Tsunami” case back etching shows typical wear. In an effort to preserve the remaining details, I’ve applied a static cling cover for protection. It’s completely original other than a replacement crystal, and post service the 20j 603 movement is keeping near perfect time. We’ve paired it with a black “tropic sport” style strap for clean period finish and easy wear. A truly rare specimen, and in such fine condition, this is likely your one opportunity to own this legendary piece of Seiko diving history.
