I have been buying picking up early '67 doxa subs. I purchased the sharkhunter 300 from a forum member. The second is a blacklung who has owned the watch from 1970. Its in amazing condition with enough wabi but not beat all to hell. Both watches appear to be unpolished and unmolested original condition. The black lung does not have any numbers scratched on the back lugs like other seen. Here is a little note from the owner:
MY STEPDAD WORKED FOR A DODGE DEALERSHIP IN 1969-1970 AND PURCHASED IT FROM SOMEONE THERE GAVE IT TO ME AS A GIFT, NEVER HAD BOX OR PAPERS, WATCH WAS PUT IN A DRAWER SINCE IT DID NOT FIT, HAVE NEVER WENT DIVING WITH IT , OR HAD IT CLEANED, ALWAYS THOUGHT IT WAS COOL LOOKING WITH THE ORANGE DIAL, WAS GOING TO GIVE IT TO MY NEPHEW UNTIL I LOOKED IT UP ON EBAY AND REALIZED IT WAS A COLLECTORS PIECE, I HOPE YOU ENJOY IT , THE WATCH HAS A LOT OF SENTAMENTAL VALUE FOR ME. I WILL TRY AND FIND A OLD PHOTO AND LET YOU KNOW.
So the question that i ask you now is what other early 300 sub do I need to look out for to make my collection complete?
