Iv got a chance to get a Rolex 679 the pat date on the oyster case is 1925 and it has a super balance movement. Question is, between what years did the oyster case only have only the 1925 year on them. Another question is would a super balance movement be correct for a mid 20s watch. Could it have been an early 30s? I dont have any pictures yet but will post plenty if i wind up getting it
