Hello Laurent. Nice example of a classic 5513. As it was said here your serial number belongs to the 1967 period. In that year a matt /white inscriptions dial like yours is correct.

For the 1961/62 period you mention the dial was glilt gloss. So your watch is correct for the serial number but made circa 1967, Keep enjoying! Abel,
My big pleasure!! Date is just a detail, the watch is original and beautiful example, that´s the important part. Enjoy it so much and thanks so much for sharing! Cheers! [nt]
