need some advice as I think I found the one. It doesn’t come with a box or paperwork but does come with a blank international warranty card. What does this card do for me and is it legit? What questions should I be asking the dealer?
Ask for pictures of the movement/caseback and for the serial number. Look closely at the case for signs of polishing (rounded edges and dulled groves). The MK40 has a sapphire crystal vs acrylic like it’s reduced brother. Ask for any service history or other paperwork. If no service history then plan on a full service in the near future.
