Rolex

I am new to vintage Rolex and looking for a while of 5513 gilt dial. Recently, I saw a 5513 1963 PCG 2 line gilt chapter ring exclamation dial. The case back is stamped 5513 III.1963. Serial is 989,XXX. Caliber is 1530. The dial looks perfect but I have s... 

Underline with swiss only sounds like a correct 5513 from 1963 in the 989,xxx serial range. Bill

It seems difficult to find 1963 Gilt Dial with exclamation point in the internet Unsure if the case back is mismatched. It looks like a 5512 gilt SWISS exclamation dial…. Best regards ...

But I am not an expert. Best, Nicolas

Is the watch on the left similar but it has no underline. This is a 5512 model. Bill Rolex 5512 gilt Chapter ring exclamation circa 1961 - 1962 ...  

What are your plans. Bill

For the past time, I researched from books and magazines. It seems that the provided picture is 5512 but with 5513 case back. May be the case back is mismatched. Best regards

it is common to find 5512 with 5513 caseback. 98x serial many found in underline configuration. But..as with rolex..anything can happen..i just wont put my money on it

With model 5513 on the case in the general 900k region. Notsure about the case back so it can exisit but as you said every thing is possible with vintage Rolex. Bill

I believe this is common, I have come across this many times. It was also shown to me in several books.

I noted the case back and serial number is matched, 5513 and 9XX,XXX.
