This is a Seiko 6119-5500 from October 1974 and it came out of a joblot of Seikos I bought cheap and have been working though. I have restored 3 automatics and 2 digital so far.
As you can see in the photos this one came badly damaged, the crystal was broken and corrosion had started to eat parts of inside of the case and mainplate of movement. That said the watch was running which is always encouraging. I stripped the movement down and serviced and it all went together fine in just a few hours. The case required some polishing just to brighten it up a bit. It has ground marks in the case top and I am not able to replicate these so have left well alone. I obtained a genuine NOS acrylic crystal and fitted in place. Matched on a sharkskin strap for now. Lug width is 19mm which is not the easiest to source so I have squeezed a 20mm strap between the lugs. I think the finished watch is very nice.
