With a case and dial layout that appear as though it were ripped right out of the gauge cluster of a Vietnam era helicopter, Seiko’s 6139-7039 is often compared to Omega’s venerable Speedy Pro. The dial is a black and white tri-level with depth and character to spare. A recessed minute register sits beneath a matte black middle, and above that, a raised hour and minute track with long and lean hash marks. Framing it all is a steep chapter with tachymetric scaling. The hour and minute hands are black and white and seem to float above the dial, and the chronograph hands are finished in flat white as well. The case is tightly contoured with short sharp lugs, sloping corners, and a recessed crown is positioned at three o’clock. A thin angular bezel, along with the beveled hardlex, adds the right amount of height, and further lends to an overall military aesthetic that sets this piece apart in the 6139 lineup. The 6139B is keeping near perfect time post service, with a snappy response from the chronograph functions. We’ve paired it with a light brown leather for a killer combo that’s as versatile as it is comfortable. From February of ‘72, it’s unpolished and completely original right down to the hardlex. The crystal shows a few light blemishes, but was too nice to warrant replacement. A permanent resident on our list of favorites, we’re certain you’ll enjoy it as much as we do.
