SOLD - Seiko 5 Sports Speedtimer 7017-8000






Following the launch of Seiko's renowned 6139 automatic chronographs by the Suwa division in 1969, the Daini division responded with their own version, the 7017, a year later. When comparing both references, the 7017 stands out for its slimmer and sleeker profile compared to the 6139.

Originally targeted towards high school and college students, Daini Chronographs were priced lower than Suwa's models (¥13,500 for this particular model compared to ¥18,000 for Suwa's 6139-6000). However, don't judge too quickly, as the 7017 featured a unique "flyback" function that allowed the chronograph sweep to be reset without needing to stop the mechanism first.



The 7017-8000 came in various dial and bracelet variations, and this particular model is the "Decimal" version. It showcases a deep matte black dial with a contrasting white minute track and an orange decimal chapter. Positioned at the top center, the Speed Timer logo in its distinctive orange color is situated between the Seiko and 5 markings. The bottom of the dial displays a 70-proof designation, a feature exclusive to the earliest versions. As a Japanese Domestic Market (JDM) variant, the day display can be switched between English and Kanji characters and is accompanied by the date under a polished frame.


This example is a new old stock and it's perfect. Chances to find a clean example are very thin, let alone finding an immaculate new old stock one!


The watch will be sold as is to preserve its condition. Servicing is possible for an extra fee. Please let us know if you wish to service it.
