and which do you prefer? i wanna get one but its expensive, and i wanna get a good one u know? like can u list the pros and cons of each? like can they both be examinable?? and how long to u gotta talk or whatever when the watch is faced to you? and would this be good for street magic?

The difference is superficial. Some prefer a silver-colored diver-style watch. Some prefer the two-tone dress-style watch. In terms of function, they are identical.

"Street magic?" Probably fine, but you'd bettter be good at mentalism or you'll just be showing off your new gimmicked watch. How long do you need to talk? About 70 seconds tops.

Before you get this, I would strongly recommend you work on Psychokinetic Time: loads of impact with nothing but a borrowed watch. Blaine did it as his first effect in his first special.

Note: Blaine did it on his second special. Anyways, I agree with Neil you should get Psychokinetic Time first. It's much much much much cheaper with pretty much the same impact if you can do it right.
