Hamilton Khaki Field Officer automatic watch

Hamilton watch, rarely worn. The watch is 44mm, like 51mm, with the lugs. Champagne dial with black painted numerals. It's just too big for me, I downsized to a plain khaki. Comes with original leather band and a khaki Nato band as well. Could not tell you the age. I do know that the watch is discontinued, so it's not very common. Comes with a box, though not the original box. No papers.
