very nice full set 1680 red submariner date.  The dial and hands are flawless and have nice aged patina.  The case is worn however doesn't look like it's been professionally polished.  The serial and ref number can be seen under magnification.  The bezel is sharp and the insert is mint.  The crystal was recently replaced.  The bracelet is a 9315 with no dater and has 12 links.  The movement is running as it should.   A really nice example of a mk4 Red Sub with the cherry on top being the original labeled box, punch guarantee and serialized hang tags
