This is a vintage used Seiko 6139 pepsi bezel pogue chrono case with no caseback. The case is 40.8mm across, 46.5mm long from lug to lug and fits a 19mm band. As shown in the pics, this is dirty, scratched and scuffed up, the inner bezel looks like it has chips, and the colors/print on the bezel is worn, unreadable or absent in spots. This is sold as is.
