    I have a 5513 (c. 1987) with the cal.1520. Should it be equiped with a hack device? When I pull out the crown to its furthest reach I can change the hands but the seconds hand continues, but winding the crown in a reverse direction moves the seconds hand back and I can even stop it by manually hacking it. The watch has a 9 million serial.

    I thought that all of the late 5513s were made to hack, but maybe not all?

    Yes, it should hack when the crown is pulled out. Regarding why it won't, well that would just be guessing, but it's possible that the balance stop spring is missing, bent, or somehow out of position.

    A caliber 1520 with a hacking mechanism? Maybe, but I don’t recall ever having seen one so equipped. Including my own 1520.

    Yes, my first thought as that the balance stop spring was the problem, but then I recall reading somewhere that not all 1520s had a hacking mechanism and then I heard that newer 1500 series movements were equipped with hacking devices.

    My 5513, Caliber 1520 does hack. It's a early 9xx Serial.

    You could be right! My 1520 is 50 years old!

    Same as mine then. Looks like I am off to the repair guy :D

    One concern was that the movement had been swapped out, but the movement serial matches that between the lugs.

    As I stated, my calibre 1520 is 50 years old. Never was equipped with a hack. I’ll check my parts listing when I return home. However, my parts list is much newer than my 1520.

    Several of the Rolex calibers added a hacking feature in the early 70s.
