Seiko 5 Sports Speedtimer 7017-6010

While much of the spotlight on vintage Seiko chronographs shines on the iconic 613X "Suwa" models, Seiko's Daini division answered back with their own 701X series, which was equally remarkable—and sometimes even ahead of its time.

Unlike the 613X's, the 701X calibers have a distinct personality, trading traditional minute and hour registers for unique design features. This particular offering, a stunning New Old Stock Ref. 7017-6010 from April 1970, is an early "Proof" dialed variant with a bold, vintage racing vibe.

One standout feature is its case: a flared tonneau shape with elegantly tapered lugs and a thick bezel inset with a sleek black accent. The dial showcases a matte black finish, with elongated luminous markers that enhance its striking design. The prominent "5" badge sits just below the Speed Timer branding, marking this as an early model with a 70m "Water Proof" indication.

The chronograph's "flyback" mechanism is an impressive feature, allowing the vivid orange sweep hand to reset to zero instantly, without needing to stop first. The original H-link bracelet, still bearing its factory sticker on the clasp, complements the watch perfectly, giving it a pristine, just-made feel.

Condition report
The chronograph is in exceptional condition, with the case retaining its original factory finishes, showing only minor, expected storage marks. The immaculate dial stands out as the centerpiece, showcasing vibrant hands that add to its charm. The bracelet remains sharp and beautifully preserved, with minimal signs of storage wear and the original sticker still intact on the clasp. The glass is flawless, free of any visible scratches.
