i am very happy with this purchase.. it keeps awesome time, been monitoring it since i got it last week and it has not missed a beat, one peeve i have is that the ball is very heavy to the point it swings too much, the bell on bottom needs to be replaced with something heavier, but i did something to keep from having to do that, on the side of the ball i dropped a teeny bit of crazy glue on each side to keep it from swinging, it was unnerving to the point you really did not know it was a watch because it was facing downward, it is a very heavy glass ball, i had to do something to fix it because i did not want to send this beautiful piece back, i am not sure if putting something heavier in place of the bell would work so i meticulously glued it into place on each side,  yes i can still wind it, but very carefully, as there is not much room between the bail and crown, but just enough to wind it, so do not fret.. i still give it 5 stars because it is worthy of it, i also replaced the cord because what they tied on here is a piece of garbage, i have some leather cord in 4 different colors i use for jewelry making and it came in handy for this item that needed a lil tweaking...  i am sure that my 11 yr old daughter is just gonna love this when she opens it up for xmas, i myself wear automatic watches and my daughter loves the movements in my watches and she has mentioned at one time or another she wanted a skeleton movement watch, i found this on amazon and said thats it!!! instead of something on the wrist i got something for her to hang on her neck, MERRY XMAS TO ALL, her father,  Joe
