SOLD - NOS Seiko Speedtimer 7017-6050





Presenting this exquisite New Old Stock (NOS) Seiko Speedtimer Chronograph Ref. 7017-6050 from the 1970s. This chronograph holds a unique distinction as the first rally meter specifically designed for rally navigators to maintain precise speed and rhythm within speed-regulated zones.


During this period, a competition between two divisions of Seiko, Daini-Seikosha and Suwa-Seikosha, emerged. While Suwa produced the cal. 6139, the world's first automatic chronograph, Daini responded by creating the thinnest automatic chronograph movement ever manufactured. With a remarkable thickness of only 5.9 mm, the 7017 set a new record as the world's slimmest chronograph movement.


The 7017-6050 Rally Meter features an unconventional design for a chronograph of its time. It possesses a single logarithmic scale that revolves around a fixed scale on the dial. Its sole purpose is to calculate speed and distance covered during a regular rally. This distinctive characteristic earned it the nickname "The Eyeless Rally" (「目なしラリー」) due to the absence of sub-dials.


Since this Speedtimer is NOS, it will be sold as is.

Servicing is possible for 40,000 JPY extra, please contact us if you would like to service it.
