SOLD - Seiko Speedtimer 6139-6031






The Seiko 6139-60XX chronographs have achieved legendary status due to their distinct barrel-shaped cases and striking color combinations. Two versions were manufactured: a larger one for export with fewer jewels, and a smaller one specifically designed for the Japanese market, featuring more jewels and additional features like the "Speed Timers" label and "5 Sports" emblem on the dial.


These JDM models are offered in unique color options and come with signature bracelets. They also provide the convenience of toggling between English and Japanese (Kanji) for the day of the week display. Despite their high desirability among collectors, acquiring these JDM references can be challenging due to their limited availability outside of Japan.


We are excited to offer a beautiful minty and rare Coke "Mark 2" Ref.6139-6031 from November 1970.


The watch will be serviced upon purchase. Servicing will take approximately 1-2 months.


Ships from Tokyo, Japan.

SOLD - Seiko Speedtimer 6139-6031

  • The chronograph is in excellent condition: The case is strong with just some light scratches. The dial is the main attraction here as it is very clean and the hands are still intact. There are no visible bumps or scratches on the outer-bezel and it is very beautiful.

    The bracelet is in very good condition and it is the correct one for this model and has light scratches and still retains its sharp edges.

    There is a thin light scratch on the glass but barely visible.
