    Minutes and seconds hands question

    Hello fellas!
    Recently noticed that, when seconds hand on my CW C60, hits the 60 seconds mark, the minutes hand is on some random position instead of being on the exact minute mark. For example sometimes the seconds hand goes nearly 15 seconds of the new minute when the minutes hand hit the mark of that minute. Sometimes is even worse, 20-25 seconds and no new minute mark has been reached. Is there a problem with the watch or this is normal Sellita behaviour?

    Set the minute hand to the correct position with the second hand set to 60...

    When you set it did you set it exactly to the second ? When the hour hand is at 12 does the second hand overlap it ?

    First you have to set it so that when the seconds reaches 12 it is exacly on a minute marker. Then it should follow exactly on every succeeding marker. That is definitely not normal Sellita behavior.

    Re: Minutes and seconds hands question

    If the minute hand is hitting at different points (and wasnt just set with an initial bias) it seems like that would mean the clutch is slipping (I mean the part that disengages the minute and hour hand when you set it, I dont know if the horological term is clutch but that's its function so imma call it that). Otherwise, the seconds minutes and hours are a simple matter of gear ratio and I dont see any other way they could fall out of alignment. Is the watch running noticeably slow?

    Re: Minutes and seconds hands question

    Set the minutes hand right on the minute marker when the seconds hand is at 12. It should remain consistent until you reset the time again, and if it doesn't then there is something wrong with the movement. It's not a typical issue with Sellita movements.

    If the hour hand is off when the minute hand hits 12, then the hands weren't lined up accurately when the minute hand was placed onto the movement - the hands will have to be removed and place back on properly.

    Thank you all for the replies!

    I did intentionally place the minutes hand exactly over the minute mark when setting the time, and the seconds hand over 60 seconds mark, but still seconds and minutes hands does not move in synchronization. I will start measuring deviation rates of the movement, but last time I did that the watch goes +6 seconds in 24 hours alongside the strange minutes hand behaviour.

    It would be good to watch it... odds are that it doesn't change over time. After you set it, there might be some slack, or play, in the movement that has to be taken up before the hands start moving together. But once they start moving together they stay that way.

    On some movements, if you move the minute hand ahead 10 or 15 minutes, and then back to the correct time when setting, it might help with this. Any pictures of how far off it it?

    Re: Minutes and seconds hands question

    There is a friction-based slipping/clutch mechanism built into all watches that allows the minute and seconds hands to move independently during time setting. Otherwise, whenever you set the time on a watch, the seconds hand would spin wildly around the dial as you turn the crown. In normal running, their relative positions should stay fixed, but if you don't align them when you set the time, you can have your minute hand halfway between minutes when the seconds hand cross the 12 o'clock mark. This isn't a Sellita or ETA or Seiko, or mechanical or quartz thing. Every analog watch will do this. If you want the minutes hand to be aligned on the marker when the second hand hits 12, you need to light it up that way when you set the time.

    On a hacking movement (movement where the seconds stops when the crown is pulled to the time setting position), pull the crown when the seconds hand is at 12 to stop it. Then align the minutes hand with the minute marker. Sync with your time source of choice and pop the crown back it. The hands should now align with the markers at the correct times.

    Sometimes there can be a little lash or play in the mechanism, so even though the minute hand appears to be right on the marker when you push the crown in, it can shift very slightly out of sync once you push the crown back in. You may need to wiggle the hand a little bit while setting to feel out the play in the wheel train.

    Couple of hours ago I set the time and aligned the hands correctly. For now everything seems to be fine. But to be sure, I will measure the deviation and will look for hands position throughout next few days.
    I hope everything to be fine, because I was having awful experience with CW customer service and don't want to go through that again.

    And again, thank all of you gentlemen!
