    Re: Watch accuracy

    I found it easy to plot my watch's loss or gain for a month, to see if the drift
    was linear.  I found that it was.  If you do this, and find a predictable drift, it
    would be easier to simply build that error into your calculations than keep
    hassling with adjustments.  I would never let the drift get past 20 s or so,
    because you can then get confusion on the minute readings.  There is
    something to be said for keeping the number of adjustments down.  I believe
    that it may affect the mechanics of any analog movements over time if
    adjustments are frequent.
    For the record, my Casio gained 13 s in 30 d.  My current analog Seiko gains
    4 s every 20 d, but I am still checking.
