1/2 scale reproduction of the already published classic spiral escapement movement. https://www.youtube.com/watch?v=vH_cjcVG7PE&feature=youtu.be It is not a clock, it is an object of decoration, to visualize the functioning. The operation is ok, but I do not advise to make it work permanently, the materials are not hard enough. I preferred to put brass pins, 2 mm brass tube and 1.4 mm commercial pin, which will be to adjust. Take care when mounting the pallets on an anchor, adjust the depth if necessary.

The weight should be about 500 to 600 grs. Fun object, helps to understand how a watch works. You will have to be a bit of a handyman to succeed with the assembly, use the sanding paper and the file. I wanted to check the operation with a 1/2 scale NOP21
