From the original owner we have a Super beautiful 1665 great white Sea-Dweller.  The Mk1 Dial and hands are original and in fantastic condition with deep patina.  The case while well worn appears to be never polished professionally but it could use one.  The bezel is sharp and the insert has faded to a deep navy blue hue.  The bracelet has moderate stretch and is originally and fully linked with the correct 585 endlinks. The movement is running +/- 10 seconds a day and keeping excellent time.  The watch comes fully complete with box, papers, serialized hang tags, polishing cloth and booklets.  It's hard to find such an original example these days from the late 70s.
