    Question regarding watch accuracy and regulation.

    I purchased an Poljot recently (late 70s) and I noticed it keeps better time when I wind it up and leave in on a shelf. If I wear it all the time it will lose about 3 minutes per 24 hours. I think it does lose some time on the shelf but not as much. (There is a possibility I am imagining this difference.

    Is this possible? If so
    Why does this occur?
    I heard it might be temperature related. Perhaps the heat of my wrist affecting watch. Or is it the movement of my hand.

    Could this be fixed by regulation?

    Hi there,

    this theme was recently widely discusssed:
    Watches tend to run slower when worn

    The short answers: Yes, most mechanical watches run slower when worn, and no, you can't reduce the difference by adjustments. So you have mainly these options:
    1) Adjust the average rate according to your personal pattern of daily motions
    2) Buy a watch, where this effect is smaller - e.g. high grade, high beat rate, or both.
    3) The economy approach: Don't move the wrist where the watch is tied around

    Regards, Roland Ranfft

    Watches display different static and dynamic rates.

    Nothing else can be generalized.

    Could it also be that my watch is stopping when I am wearing my watch and I just don't notice because I haven't observed it yet.

    Could yesterday's solar flare have something to do with it?

    Considering the miniscule amount of mass converted, any changes to the time space continuum at a universal level would be difficult to measure with conventional apparati.

    A good read on watch adjustment and regulation is the TM 9-1575 manual (free, not too long, explains the jargon instead of assuming it).


    Just as with dogs and cats, the reaction of your watch on solar flares will depend on your own. If, upon hearing of the flare, you dove under the nearest desk or table, or flung yourself across the room to hide under the bed, chances are you knocked your watch on something. It would notice that and react.

    I opened the watch up and noticed that the balance wheel "wobbles" slightly as it moves. Could this be the cause?

    As in:

    broken balance staff pivot (or hole jewel)?

    or

    bent pivot(s)?

    or

    bent balance wheel arms?

    or

    distorted balance wheel rim?

    (Is the wobble more pronounced in certain positions? DU?DD?CU?CD?)
