1972 Seiko 6138-0017 Automatic Chronograph UFO / "Yachtman"


The term "Yachtman" appears to have been of questionable origin as it pertains to this particular chronograph, and clearly because it looks right at home trackside, far from any body of water suitable for yachting. Without a doubt, the 6138-0017 and its Speed Timer counterpart are 1970's racing for the wrist. The unpolished case is a beastly 44.5mm of sloping contours and smooth case lines. The minty bezel is the standout feature here in black with a fiery metallic red inner track scaling the tachymeter. Beneath it the minty dial is a flat black off set by opposing sub registers in matte silver. The larger of the two counting minutes, and it's smaller partner above tracking hours. The hour and minute hands are contrasted in a bright white, and gliding around the dial, the long and slender yellow sweep. The luminous material is the original and sports an almost khaki patina that’s fairly even throughout. The 6138 offers independent quick set of both the day and date, and can be manually wound. The chronograph functions are crisp and responsive and post service, its keeping near perfect time. Completely original aside from a replacement crystal, and on the original “three-link” stainless steel bracelet, this example from July of ‘72 is possibly the perfect vintage racing chronograph and sure to earn a regular spot in any rotation.
