    Default common clock question

    Can any harm happen to the teeth of wheels of a clock
    If the hour hand is moved backwards a little?

    The short answer is that "something" can get damaged if you move the hand back. But normally it depends on where the hand is. Some clocks will state not to move the hand backwards if it is in the quadrant between 15 minutes before and 12 o'clock.

    I am sure there are other examples, and the folks here will provide more info.

    If we are talking of the hour hand rather than the minute hand, then on most clocks you are not likely to damage anything if you move the hour back a little.

    But it might help if you explained a little more what you are wanting to do and why and on what sort of clock.

    The most likely scenario in most clocks is that the main damage that can occur when moving the hour hand is when it may stick, you are likely to bend or break the hand itself. Most hour hands are intended to be moved a little, gently. Any resistance, then try something else.

    If it is a quartz watch there is a risk of damaging plastic wheels.

    It depends on the clock.
    If the clock is a rack and snail strike, and the hand slips
    the strikes will be out of sync.
    In general is it not recommended to turn the minute hand backwards
    one chiming and striking clocks.
    This is not always true as some talk case clocks ( grandfather clocks )
    are specifically designed to be turned backwards.
    All clocks can be turned forward with the exception that some
    can be damaged if turned past the next strike or chime while it
    is still running the previous strike or chime. In these cases it is
    always best to pause after each strike or chime to allow it to
    complete.
    Many alarm clocks should not be turned backwards.
    I don't think the hour hand is usually strong enough to strip
    teeth but I wouldn't generally recommend attempting to adjust by the
    hour hand.

    Many alarm clocks cannot be turned backwards past the alarm hand.

    It depends on what kind of clock you are speaking of. It would be very unusual for any damage to be done to the gearing in any case. The damage is usually to levers and lifting pins. Starting around 1900, most clocks are designed so the minute hand can be turned either way. On some clocks the instruction sheet actually recommends turning the minute hand backwards to set the clock, or to sync the strike on older clocks.
    Post a photo of the movement you have and people on this list can answer your question about a your particular clock.

    On many striking clocks the instruction does say to work the minute hand back and forth between 11:45 and 12:00 to synch the strike.

    Do you mean the minute hand?

    Here is,what I think the OP is getting at. You just used the minute hand to figure out how it strikes before installing the hands permanently. So the clock strikes 6 times. Ok so when he pressed on the hour hand it did not press on so the tip is perfectly at the 6 mark. So he wants to move back the hand slightly instead of pulling it off and try again. To answer that question yes you can do it. The hour hand is,just a pressure fit and will just spin on the hour cannon. The hour cannon though will not move thus no damage will be done. But on the flip side I wouldn't go doing that a lot because you'll eventually wear the hand bushing enough that it's loose

    Nods. Yes this is only meant to be occasionally used.
