I'm building a wristwatch case (that's why this is only slightly ot) and I
need to find a watch winding mechanism. This is a small ac motor with a
timer that rotates a watch (usually 1 out of 4 hours) which keeps the self
winding watches wound/running. I've done many searches, but can't seem to
find someone who sells the timer/motor mechanism only. Knowing diverse
knowledge base here, can anyone help me?

I agree, there are many work-arounds and yours and Puckdroppers are good
ones, but I'm building some boxes to put into a high-end watch dealers store
and the clientele expects certain things, a specific-use winding mechanism
being one of them ;-)
It sure has been a devil to find a mechnism-only supplier.

Actually, these cases will be for people who have multiples of these
watches, so no matter how much they move, the watches will wind down before
the next wearing, but thanks anyway. Of course, I guess they could wear
them all at once, but that's not too fashionable, I suppose....

Don't choke on the price.
With as few mechanical watches as there are, and the cost of those watches,
its nothing. They don't own the watches because of their accuracy, since a
simple set of Singapore guts keeps as accurate a time as they do. Not
sensitive to positional gains and losses, either.

Yeahbut, he wants to build a wrist watch, not a forearm watch...

There are also DC gear motors that might work, such as this one
(probably for a single watch - don't have one to test) which provides
3 RPM at 6 volts and 6 RPM at 12 volts
http://www.allelectronics.com/cgi-bin/item/DCM-245/400400/6_RPM_GEARHEAD_MOTOR_.html
It just needs a 6 volt "wall wart" type supply.
What I remember from years of wearing self-winding watches is that the
winder moves with CW or CCW rotation of the wearer's wrist - which
makes me wonder whether a reversing motion would be an option (versus
simple rotation). It would certainly makes the winder more
interesting to watch ;-)
Using a DC motor makes reversing the direction of rotation very easy
and I see the possibility of building a complete reversing drive unit
(for one watch) with varying CW/CCW periods (1 second each direction
to 1 hour each direction) and an overall shutoff timer for maybe $40 -
$45 in parts using the above motor and a $4 microcontroller.
If you just want one direction of rotation with varying on times and
an overall timer, parts would be $30 - $35.
For a few dollars more, the winder could have status lights (maybe red
for "winding" and green for "wound") or even play a short tune when
finished. How many "bells and whistles" would the market support?
If you're interested in pursuing this, go to www.picaxe.us and email
the webmaster (me). I'm retired and always looking for interesting
projects.

Hamster and exercise wheel. Have the only watch that
runs on alfalfa pellets.

Take a look at: http://www.geocities.com/dbfritts2001/watchwinder/Homemade_Watch_Winder.htm
McMasters-Carr seems to be the place.

If you want bells and whistles, I'd design it so that it always
stopped with the watches facing front and upright. Maybe use a spring
/ escapement mechanism so that the watch always made a full turn back
to its original position. Then, use a timer so that it only ran when
it wasn't likely to be seen, or show off the escapement mechanism by
having it run all the time!

Is vibration good enough to keep the watch going? You could get one of
those little cell phone vibrator motors (with counterweight), and maybe a
555 timer, a few capacitors and resistors, and for less than $10 you've
got yourself a portable, battery operated watch timer.

As strange(read weird) as this may sound, had a friend with two of these
type watches ,one dress and one everyday. He resolved this problem with a
self designed cheap "metronome"! GI ingenuity <G>

Have the person wearing the self-winding watch move once in a while and
save the cost of the motor? ;-)
