[llm3000]

Hi all, i am going to view this watch tomorrow. Want to gather your pro opinion to see if its legit. its a 1967 5513 with meter first dial and USA jubilee bracelet. My initial observation, the circle lumes was done badly around the edge, insert should be serviced one (i have a kissing4, so not a problem), i dont have knowledge about the USA bracelet, but the endlinks for sure not fitting properly. and case back engraving...numbers 5513 looks weird, almost like it was done twice over each other. Its my first 5513, pls enlighten me thanks!
