Vintage Seiko 5 Sports SpeedTimer Chronograph ref. 6139-8050 Green dial – JDM, Serviced, 1975

Seiko’s automatic chronographs, especially those produced in the 70s, occupy a special place in people’s hearts. So special, in fact, that certain enthusiasts have built their entire collections around the fabled cal. 6139 – Seiko’s first self-winding chronograph movement – and its worthy successor, the cal. 6138. And why wouldn’t you?
The two movements power some of the brand’s most acclaimed watches, including the Pogue, the Kakume, and the UFO, not to mention the entire Sports 5 Speedtimer line. The one we have the pleasure of offering here is among the rarer of the bunch.

This ref. 6139-8050 is a stunning JDM variation of the model, which incorporates the highly sought-after 6139-8090T dial surrounded by a quite unique stainless steel case. The latter, as it so happens, is in very good condition, with all of its edges having remained preserved through the years. The remarkable color palette of the dial is gradient of green and is complemented by the cold glint of the steel that surrounds it yet simultaneously contrasts it, serving as an aesthetic centerpiece and lending the watch an inviting warm luster.

Our offering is in very good, entirely authentic condition. Neither the case nor the dial have been refinished or otherwise tampered with, and all internal and external components are original. The serial number puts the production date in November 1975. Comes a black leather strap. The cal. 6139 inside was just serviced by our in-house watchmaker in 04.2023 and is ticking perfectly.

Covered by a limited warranty of 1 year, starting on the date of purchase.
