A friend of mine who is only 18 y/o has the Big Bang in Rose Gold Hublot. For some reason I feel like it is FAKE! He showed it to me today and let me play with it. The hand stops moving because he states "you have to shake it in your hand a little for it to start moving again". What does that mean? He says he has to take it back to Hublot to get something fixed, weird eh? The back of the watch is glass, so you can see through the automatic movement ticking. I know the approx. price of Hublots, but what would this one be worth? It is Rose Gold Big Bang Chronograph with Rubber Strap and Carbon Fiber face. ALSO: he dropped the watch on its face, glass didn't crack but the rose gold metal was dented in and scuffed, and it is colored in a stainless steel type of color. I would assume Hublot's are made purely of gold, no stainless steel unless you buy a stainless steel one, so why would it chip to a stainless steel color?? Here's a pic of what his watch looks like.

It means it is broken and possibly a fake. Nothing today is pure gold. If you take it to a place that buys gold they will test it for you.
