Though Seiko’s Suwa division famously released the 6139 automatic chronograph in 1969, it was only one year later that the Daini division answered back with their own iteration in the form of the 7017. Thinner and sleeker than the 6139, it could be delivered in a more compact package, and featured a “flyback” function that allowed for the chronograph sweep to be reset without having to first stop the mechanism. At the time of its release, the 7017 set the record as the thinnest production automatic chronograph in the world. Similar to many other Daini models, the entire 7017 lineup was built solely for the Japanese domestic market. This example from July of ‘71 features a hard to find “minutes only” dial configuration. The soft matte black is contrasted by crisp white Arabic minute/second markings, along with the Seiko and “5 Sports” insignia. The Speed Timer designation in fiery orange just above the six. It’s framed by a “count up” rotating inner bezel with silver and steel gray blocking. The hour and minute hands are polished beveled batons, and the chronograph sweep in blaze orange can’t be missed. In JDM fashion, the day can be toggled between English and Kanji, and is paired along side the date under a polished frame. It comes attached to the original “5 Sports” bracelet that’s a double hinged block design. The tonneau case is nicely contoured, and the flared sides make for comfortable daily wear. It’s unpolished and completely original aside from a replacement crystal. Post service, the 7017 is keeping near perfect time, and the “fly back” chronograph functions operate smoothly. With a dashboard layout, its vintage racing for the wrist, and sure to earn a regular spot in your rotation.
