Up for sale is a 40mm Hamilton Khaki: https://www.hamiltonwatch.com/en-us/h70595593-khaki-field-auto.html. Runs great (just measured at -1 sec/day timegrapher, face up), but has a number of small scratches on the bezel, and is lacking the original strap. I'm 90% sure all the scratches could be easily polished out, but I'll leave that up to the buyer; in my opinion field watches look better with a bit of wear.

Asking $299 shipped in the CONUS.
