Several years prior to releasing their first automatic chronograph, the 6139, Seiko had chosen to commemorate the arrival of the Olympic Games in Tokyo by introducing two newly designed and specialized references that would mark major milestones in technical development. Released in tandem were the 6217 World Time (GMT), and the 45899 (5719) Chronograph (60 sec./ Mono-Pusher). Both models bore an “Olympic Torch” insignia etched into case back, but before the year was out a second chronograph model, the 5717-8990 would be released as well. The 5717 added a date complication, and this variant was embossed with either the insignia of the upcoming Asian Games, or the standard “Sea Horse” motif on the case back. These first chronographs were built on the hand wound Crown movement base and utilized a column wheel design, along with horizontal coupling to drive the sweep around the dial. A single pusher worked to both start and stop the mechanism, aa well as reset. This example from December of ‘64 is mind blowing. The dial is a lacquered white sunburst with polished baguette markers, and a date aperture at three o’clock. In contrast, it’s framed by a raised black chapter with a white minute track, and the lettering on the dial is a minimalist print that contributes to the crisp, clean aesthetic. The case is bold, but simple. The lugs are long and tapered with a clean bevel along the outer edge. Typical of this model, the “Sea Horse” design and other case back etchings have mostly worn away, and are only visible with close examination. The black “count up” bezel sits prominently atop the case with a staggered knurling along the edge, and white inlay in the engraved markings. The bezel for this particular model is made from a plastic material, and vulnerable to breaking, wear, and paint loss. This one is absolutely the nicest example I’ve encountered. The knurling and corners are razor sharp, and the inlay is a completely intact, and clean bright white. It’s unpolished and completely original aside from a replacement crystal. Post service it’s keeping near perfect time and the chronograph functions are crisp and responsive. We’ve paired this one with a premium black grain leather with white stitching for a striking finish that’s sure to make this incredible piece of Seiko history the highlight of any roster.
