One of the less seldom seen Seiko chronographs of this era, this all-original Japanese Domestic Market (JDM) 1970 Seiko 7017-8000 Speedtimer flyback automatic chronograph features a flyback chronograph, which allows the user to reset the chrono function without resetting the time completely – similar to that found on Citizen’s 8110 bullheads – but rare on Seiko watches.


Another unique feature on the 7017 series was its quite “short” calibre of only 5.9mm, and it was only in the late years of the decade that this was bested.  The 7017 – similar to the 7015, but with key distinctions – was a JDM variant only, and wasn’t exported outside of Japan; it also wasn’t made for more than a handful of years in the early 1970’s.

Seiko placed their movements into multiple highly unique cases, leading to a plethora of out of the ordinary shapes and sizes, not to mention allowing them the ability to stand out on the wrist – this less common Speedtimer is no exception.

This Seiko 7017 comes with a light brown leather strap, NATO strap, springbar tool, and Pelican travel case.
