Help with unusual style watch

[dross]

Can anyone tell me anything about this necklace timepiece? It appears to be Swiss in 19mm diameter ball surrounded with blue enamel, silver lace work with diamond chips, The dial is 11mm diameter. Rotating the top with the crystal winds the mainspring. One picture shows 1 of 3 blued screws that hold the top bezel on case. On the left side of the same picture the raised brass screw will set the hands. Sorry for the poor pictures my camera and setups are limited.

These are great movements. I think they are called plateau movements.

The wheels are stacked with the balance taking up the third (middle ) plate I think.

Very very cool.

1940's I think.

maybe earlier.

Why did you post this same thread twice--20 minutes apart?

Maybe Jeff will delete one for you!
