A classic vintage Seiko chronograph, this reference 6139-6005 represents one of the earliest automatic chronograph designs of the 1970s. The 41mm stainless steel cushion case offers a bold yet comfortable presence on the wrist, true to Seikoโs distinctive sport watch styling of the era.
The dial features a clean chronograph layout with a single subdial and day-date display at 12 oโclock, paired with a red and blue โPepsiโ style tachymeter bezel that gives the watch its signature vintage look. The design is sporty, highly legible, and remains one of Seikoโs most recognizable chronograph configurations.
Powered by the Seiko caliber 6139 automatic chronograph movement (17 jewels), this timepiece highlights Seikoโs innovation during the early automatic chronograph era. It is fitted with a Seiko stainless steel bracelet sized to fit up to approximately a 7โ wrist, recently serviced, and backed by our 2-year Romans Jewelry warranty.
