This is a Seiko 7005-8040 from 1970. I bought this one from a watch fair with another piece and paid £20.00 for the two. I was taken with the dark mat blue dial and the black marked hour indices. It was a non runner and also not the original bracelet. Opening the back of the case I found that the hairspring was beyond repair as it was completely tangled. I was fortunate to have a donor so I placed that in to test if it worked. I my relief it did so I then stripped down the movement, cleaned and serviced and put it back into service for many years to come.
