bibbles10504: i find though that it is defenetely easier to do the watch steal with bigger hands, then you can just move the watch more without using your whole hand.
I do not understand what you mean about moving the watch more without having to use your whole hand. Not sure what technique you are using and for which type of watch. A buckle type latch should come off in about 3-5 seconds with proper practice. If you are doing the watch steal during another trick as cover then of course you can delay the steal according to the flow of your performance.
Kristian in response to your question, as far as I know Chappy Brazil's Watch Steal is only out on video.
