Hi, this exact thing happened to my 005 from Josh after around 3 days. I took it into my local watch maker a week ago and he said it didn't need a whole new movement and just needed a couple of new small parts as they had broken. Only $50 with fitting, but I'm still waiting delivery of these parts (and we're not 100% that he can get the parts from the EU disty that will work with the asian 6497 version of the movement). What was the outcome of yours?
My back up is just getting a whole new movement installed, which I prefer to sending it back (out of stock anyway). It would be less than $100 either way for me and considering the quality of the watch I'm not too bitter about the situation.
