This is my Seiko H357-5030T, I have not seen an identical one on e this site - but there were many versions of the H357 around.
This version is an alarm chronograph, black faced, Note the lack of studs at the corners of the face - many H357’s had those, but not this one. This was a very dressy elegant watch in its day -much copied by casio at a later date.
I hope the pictures are good enough for your library, please feel free to manipulate or crop them if you need to.
