WTB Rolex Submariner 1680 Red All Original and Excellent Overall Conditions

[Franks07]

I am looking for a true "investment piece" and am prepared to be very patient awaiting the right example at the right price. Box & Papers are desirable but not a deal killer for the right example. Must be all original with an excellent case inclusive of fat and even lugs and bevel edges present. Mark IV is my target reference but will consider all examples that meet my purchase criteria.
Thanks!
