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 color ways (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. From June of 1973, this blue dialed variant is in outstanding condition overall. The dial is a rich navy with a soft velvet texturing. There are a few very light blemishes visible in the finish under direct light, but nothing that breaks the paint, or draws attention. The luminous material on the markers is the original, and has just begun to develop a light even patina. The rotating inner bezel has faded to an even charcoal gray, and the silver markings are still crisp and easily legible. The hour and minute batons have retained their bright polished finish aside from some light oxidation around the windows, and some color is visible in the original luminous. 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 shows almost no wear or fading. The case is unpolished with some light signs of wear, though the original finishes are still crisp throughout. The case back is engraved with the original owners name and what appears to be a social security number. It is otherwise clean with no tool marring. The chronograph functions are snappy and responsive, and post service, the 6139B is keeping near perfect time. We’ve paired it with a supple “Tropic Sport” style strap for a versatile period finish that’s comfortable on the wrist.  Completely original aside from a replacement mineral crystal, it’s an absolute head turner that’s sure to be the new front runner on any roster.
