Seiko's 6139-60XX chronographs have achieved true iconic status. Their distinctive barrel-shaped cases and bold color combinations make them instantly recognizable and often serve as a catalyst for converting new enthusiasts. As with many of Seiko's early chronographs, two versions were developed in parallel: a larger production export variant with fewer jewels, and a smaller production model with a higher jewel count exclusively for the Japanese domestic market.
 
In addition to the extra jewels, the Japanese Domestic Market (JDM) 6139 models, along with other references, were given the nickname "Speed Timers" and often featured the "5 Sports" badge on their dials. Appropriately, the day of the week function could toggle between English and Japanese (Kanji), and these models offered unique color variations and signature bracelets that were not available in the export versions.
 
These JDM references are highly sought after by collectors, but their limited availability outside of Japan makes them challenging to acquire. That's why we are particularly thrilled to present this exceptional timepiece from May of 1971.
 
The chronograph functions on this watch are precise and responsive, and the reset to zero is quick and sharp.
 
Upon purchase, the watch will undergo servicing and cleaning, and the glass will be replaced before shipping. Please note that shipping may take 1-2 months.
