Base metal case (plated?), stainless back with matte silver linen finish dial bearing slightly raised black numbers at 6, 9 and 12 and black sticks at other positions. Date window at 3 position. No exterior serial number. Hand wind with quick set date by pulling crown out to second position and fully depressing. By looking at it, I'm going to say it has never been opened. Received as seen, I wound it up and put it on......keeping perfect time and date changes at midnight. I find no case wear to base metal on bezel or lugs, so I'm unsure what case composition is.
I thought this was going to be a tough one to ID, However when I opened the first 1977 linebook, it was listed on page "XI" of the table of contents and on the first page of photos.
1977 Bulova Model 10400-0W
