Seiko. Ref 6139-6005. Dated May 1971.

This is fully serviced and keeping time. All functions work including the rotating inner bezel.

A complete overhaul was done a few years back by a WOSTEP trained watchmaker. Google Fankhauser Watch in Salt Lake City. To get a better idea what Chris does.

The hands and crystal are not original to the watch.

I searched all over the world to get the gaskets and seals so this would pass 5 bar water resistance. Which it does!

I added a longer clasp with more adjustment holes because this bracelet was short. It is seen on my 6.5 inch wrist with two more holes for larger adjustment.

Selling to fund another watch.
