Hi Jim:
It may not be a good idea to adjust the watch so that the frequency is
spot on at the time the adjustment is made.
A better idea may be to wear the watch for a week and note the
fractional time error then adjust the frequency so the offset matches
the error.
Have Fun,

Hi Brooke,
I've adjusted the watch as best I can within the limitations of the trimmer.
The waveform was drifting 10 microseconds (slow) in about 20 seconds and so
this should come out to 1 second in 23 days.
I have now set the watch accurately and will follow it's progress. I plan to

Interestingly, the module has a pad that gives off a stepped square wave at
32768/48 Hz. So with well calibrated equipment (which we all have of course)
it is trivial to adjust the trimmer to put the watch back to decent
accuracy. Using the smallest adjustment of the trimmer that I could

Referring to the post with the mechanical procedure, you
determine the offset over a couple of weeks. When you
open the watch to adjust it, you apply the offset to
whatever frequency you find when you open the watch.
I don't wear a watch when I sleep, and that becomes part
