You can tell with Hublot's easily as they are a watch maker who use innovative materials in their watches, just by the look of the watch you can tell its fake, the glass is not even crystal sapphire. Here's the real big bang in rose gold, look at how many discrepancies there are between this one and Nick's I counted 10, from the seconds hand being in red, to the actual numbering of the inside dials and everything about is OFF....I would piss my pants if someone ina club wore this next to me.
