I'll use one of WUS's favorite words "rare" in this case as there were only 100 made, the Lum-Tec 300M-4. This is one of the only 300m's with the miyota 9015. Honestly the stock rubber strap is stiff and uncomfortable so It's on a Barton canvas now and I'm including a Barton silicone with matching blue. Some minor scratches here and there on the case and what looks like on the AR coating. I tried but can't seem to capture the AR marks in my pics. Asking 400 shipped. It'll be a heavy package at about 2 pounds.
