Hi Zaf,
I have a JLC cal 900 automatic. I would like to know how many jewels this movement had and the time frame of manufacture of this particular calibre please if anyone has this info. Also I don't know if there is a problem with the movement as when the crown is fully pushed in it moves the date on by one day by winding the crown one turn clockwise. When the crown is pulled out to the first position this sets the hands. When the crown is pulled out to the second position the date moves again but more slowly (2 rotations). The question is that there is no position for winding the watch. I have known some Seikos to be like this but a JLC?
Any help would be appreciated.
regards,
Greg.
