Most of the offerings in Seiko's 6139 line up are quite easily recognizable, but one variant stands alone in it's architecture. The "Pulsations," as it's more commonly known, is an eye-catching doctor's chronograph with features all it's own, and an undeniable presence on the wrist. This example from September of ‘69 boasts a flawless navy blue dial with a subtle sunburst and matte finish. The markers are applied polished blocks paired with thin polished baton style hands. The chronograph hands stand out in a flash of brick red, and the sweep is the correct “two piece” design only available on the earliest models. Just beyond the dial is the rotating inner bezel in a glossy black and silver that is laid out in a "Base 10" scale for determining a resting heart rate. The case sports a low profile bezel and sculpted lugs, and has a thinner profile perfect for sliding just under a crisp cuff. This watch is in near museum condition considering it’s been around for nearly a half-century, and original examples are becoming impossible to find. The navy blue dial is also scarce, as it was only produced for earlier models, and the same can be said for the English/Chinese day wheel. In the only instance in our history, this one is still attached to the original “chiclet” style bracelet. It truly doesn’t get better than this one. The 6139B is keeping near perfect time post service, and the chronograph functions are crisp and responsive. Unpolished and completely original aside from a replacement crystal, this one checks all the boxes for even the most particular collector.
