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. From the “Pepsi” tachymetric bezel, the the “H-Link” bracelet, 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. From March of ‘76, this is a fantastic example overall. The golden sunburst dial has just a touch of character. A few light blemishes mark its surface, but the color and finish is even throughout. The hour and minute hands are lightly oxidized, and have been carefully relumed to match the plots on the dial. The original luminous material on the markers has only a light patina, and slight darkening at the edges. The chronograph hands are bright red with no chipping or paint loss, and the inner bezel is a rich even yellow throughout. The case is unpolished and the original finishes are still intact. The outer tachymetric bezel in metallic red and blue has an even fade and moderate wear, but the markings are still clearly legible. We’ve paired it with a olive drab RAF NATO that complements the dial, and is comfortable for regular wear. Post service, the 6139B is keeping near perfect time, and the chronograph functions are crisp and responsive. Aside from a replacement crystal, it’s completely original, and a great opportunity to own a watch that has reached near “grail” status among collectors. Don’t miss this opportunity to add this historic Seiko to your own roster.
