This was a fun project to put together. It works pretty god considering it is mostly plastic and it does a great job showing you how a Tourbillon works. The main spring has a lot of power and it runs for quite awhile. Unfortunately it came with some strange QR code that did not work to download the instructions. However, if you any knowledge of how a watch movement works it is not difficult to figure out with looking at the photos on the site. I think half the fun was not having the instructions and having to figure it out. it was a lot of fun and I would recommend it to any watch enthusiasts. I am thinking of taking it apart and painting it with metal paint of using rub and buff on it to make it look more real.

Parts came in great shape. Little or no burrs. But no directions. Had to ask for directions to assemble. The mechanism skips at times, not quite right. But runs enough to get the idea on how it workd.
