The 6139 series is one of the most historically significant chronograph movements ever produced and remains highly collectible among enthusiasts as one of the world’s first automatic chronographs. This example features the distinctive Speedtimer design and original JDM day wheel. The watch is being sold for parts or repair. One of the hands from the lower chronograph subdial has fallen off and is loose inside the case. A photograph of the loose hand is included in the listing.

Beyond these issues, the watch appears to be running and holding accurate time. However, for proper operation and continued reliable timekeeping, the watch will require service or overhaul.
