I've researched this watch for hours, and I'm stumped. My resources are limited, though, so I'm reaching out to you fine people! Hopefully we can figure out what it is.
Manual winding, with a chronograph, I'm guessing it's a uni complex from the information I scrounged up
17 jewels, 820 movement.
78210/1FT is stamped on the bottom left side, 25582 is stamped on the right.

Anyone familiar with it?
