This can work for any watch that chicks notice and comment on.
I personally have this watch that flashes at random times
and chicks love it and come up and open me because of it.
Her: Nice watch, why's it flashing?
You: O that, when it flashes it uses beta waves to give me information about my
surroundings.
Her: Wow, whats it saying now?
(make up something that is NOT happening or uncertain)
You: It says your going to buy me a drink/It says you've got a crush on me/
It says your wearing no underwear.
Her: No ...... (usually some form of refute to your claim)
You: (Tap watch) Hm... must be an hour fast.
Alternatively you can instead of the hour fast bit, start teasing her about being so
forward by having the crush or going to buy you the drink, acting as though
the watch said it so it must be true.
This usually has them laughing and can lead to your prediction happening then or
sometime later.
If you want to try it but don't have a watch try
