For vintage Seiko lovers, perhaps no series is as instantly recognizable as the 6139-600X models that have become synonymous with the introduction of this historic movement. For collectors, they serve as the embodiment of Seiko’s efforts to deliver, with style, their first automatic chronograph. Today, these models are often referred to as, and fall under the umbrella of the “Pogue” models due to their association to Col. William Pogue and his now historic yellow dialed variant. Available in three colorways (Yellow, Silver, and Blue), it goes without saying that no matter your preference, they are all memorable in their own right and the right example would be a highlight in any collection. This example from February of ‘73 is amazing. The rich, velvety blue dial is flawless and captivating. The luminous material on the markers is the original, and free of degradation. The rotating inner bezel is without fading from UV exposure, and is still a deep black in color. The polished hour and minute hands show some slight oxidation, but the luminous material has no discoloration or degradation. The chronograph hands are a fiery red/orange that is both complementary, and in perfect contrast to the dial. The outer bezel in crisp, metallic red and blue bears only minor signs of wear, and no fading of color. The case remains unpolished with the original factory finishes still clearly intact. We’ve attached it to a heavy, two-piece RAF NATO in soft gray for a casual, comfortable finish that offers great versatility. It is unpolished, and completely original aside from a replacement crystal. The chronograph functions are responsive, and post service, its keeping near perfect time. It’s a beautiful example and would make a great addition to any roster.
