This is an interesting thread as I just today got my archive back and found out that my watch was produced on October 29th, 1968 and is a 321, 145.012-67 caseback. I did a search and could not find a single watch produced after mine with a 321 movement. If any watch should be a -68, it should be this one. Has anyone ever seen a 145.102-68 caseback?
