A question.  I was playing with my kid today with my Sea Devil on and happened to hit the carpeted floor with my hand and noticed the watch was shaking.  A couple more tries and I figured out that it was duplicatable and you could hear the mechanism shaking.

Is this a problem?  Is it normal?  Is it anything????????  I have several autos and never once noticed such a thing before.

Thx.

Sounds normal for an auto... Once in awhile you get it just right and the rotor really gets hummin'. Should be cool.

I figured it wasn't broken, per se, as the watch is accurate.  But the watch was literally shaking my wrist in that one position for a few moments.  I assume that its just the rotor getting some centrifugal force, but it was weird, non the less.

Yup... I have had it happen many times. The other night on my new Moray and quite often on my Omega's. I am sure someone more horologically endowed than I will chime in, but I think all is well. It is an odd feeling though, you can literally fell and see it shake!

Precisely.  My Seamaster's rotor is a whisker quieter, but I've never noticed the dance before.  

Thanks for your response.

Yea very normal for some movements to really go. The Swiss eta 7750 has a nice wobble to it.

The Miyota and Valjoux 7750 use a unidirectionnal winding mechanism, therefore when the rotor swings on the free side, which is clockwise on the Miyota movement, helped by a hit or hard shake, will make the watch to wobble on the wrist, which is totally normal. I guess this is what you experienced with your SD. Hope it helped
