That is wrong. The 1960s funny U that you show is actually a later 1970s design, introduced with the Quartz and Golden shadow design. You will not find that logo on 60s UGs. Whoever compiled the dates and logos legend, has it wrong ...

nina and evil nina production started much earlier than 65. Difficult to put an accurate date on it, but serial 2.2 mill is about the earliest I have seen. The logo on dial was the earlier applied logo, however, the crown has always had (as far as I know), the later 60s logo or linear U. The model started out as a 22706-1 and -2 which used the famous valjoux 72-6 or caliber 130 (same as rolex daytona) movement not the later caliber 85 (not as prestigious).
