When your position just doesn't get it done...

[WatchinMD]

So my new BLNR was about 2 seconds slow in the last 2 days in spite of wrist time and resting face up at night. I hypothesized that it was the axial rotation of wearing movement that would tend to make the movement gain time. To test this I suspended the watch head down but level, holding the open clasp segment between 2 fingers. Then I applied short rotational oscillatory movements for a few seconds. Voila! the watch had gained 2-3 seconds and is now about +1 second.

I searched the forum and found a ton of accuracy threads but did not see this mentioned.

I assume this is not detrimental to the movement. If not, it seems this is a much more convenient technique foe dealing with a slow watch than hacking it, setting it a minute ahead and letting time catch up.
