Everyone agrees "Skinny 4" is an early version around 63 and then those later adds show what seems to be the same insert. My bet is that the adds back then weren't always accurate reflecting the exact dial/insert version being sold in a given year. Perhaps service manuals would be a better indicator
Anyone recognize what 5513 dial variant(year) the add shows. Does it look like a 67 dial when the add was printed or a 64 dial? Reason I ask is that "Skinny 4" inserts have been seen on early 1964 watches and perhaps the image although in a 1967 add is that of a1964 watch. Thanks, Daniel
I've yet to see this insert on anything other that 1963 5513 's I'm sure other years are possible. Perhaps Rolex was using older images in their adds. Do you have dates on those? Daniel
