this watch looks good, the stack without mechanism works very well by simple movement of the handle, it restarts immediately, and it should stay about 10am on if you let it rest ... something for risers -tard. Small snag, there is a lot of serrated wheels that seem to be part of the mechanism. there are really only 2 spinning wheels (which are located in the axis of 50 and that of 35. They are hidden by other bearing is not running). short, not so skeletal that ... but this watch is working. I recommend this purchase.
