    King seiko 0852 need help with regulating screws

    Hi guys

    I have a king seiko quartz 0852 8000 that is lagging about 2mins/day. May I know which screw should i turn to make it go faster?
    Picture of movement attached below:

    At two minutes per day, I am not sure the trimmer condenser is going to be of much use.
    Ask me about 4 MHz watches

    Does that mean there's something wrong with thee IC?

    Anyway, may I know which screw do you adjust? Might be worth a try :D

    Unless the battery is on its way out or someone in the past went crazy fiddling with the trimmer condenser, then yes, I would suspect that the IC is faulty.

    Still, if you want to give it a go, I think the trimmer condenser is here :

    I gave the screw a few 1 deg turns clockwise but the time is still lagging. Then I saw that the movement of the second hand was irregular. Sometimes it ticks at 1 sec, sometimes at about 1.5-2 sec. Does this confirm that the IC is faulty?

    I would think so.
