I have found locally a pre owned calibre 16 500m auto. He is asking $1100. From my online research, this seems like a great deal. He is also including service history paperwork from a well known jeweler in my city. He also threw in a watch winder that cost about $150. I am meeting him in the morning. The pictures attached are before he had it lightly polished. i know some folks say not to polish but he says it looks phenomenal. The box he said is in bad shape from his young daughter playing with it? but he does have the box and papers. My question is for opinions on if I am getting a good deal. The lowest online price I have seen for a pre owned is $1600 ranging up to $2500. Retail is roughly $4k. Any thoughts?
