I was told that this is a 5513…the pointed crown guards (I have learned they are actually “eagle beak” crown guards) have been bugging the heck out of me…the pointed crown guards on a 5513 were only made for a short amount of time…and it only had a gilt dial (gold writing not white)…however I’ve confirmed the birthdate of this watch 1962 and that it is a 5512 NOT a 5513…and for only about 2-3 years did they make the 5512…with 2 lines…much rarer…with my dial and eagle beak crown guards… and this is not a 5513 but is a 5512 2 liner as I’ve been able to confirm in my research…because in ‘63 or so they added 4 lines including the COSC wording…the only thing that is not (to me) original is the bracelet which has a 1975 date based on the stamping.
