What do you think of my planned retirement prank?

I’m retiring on or about January 1, 2015
I plan on a prank on retirement day in which the company CEO sends me a gold Rolex. I bought this fake Rolex from a company in China. I plan on having it delivered to a company retirement party for me with the below letter. I’ll try to present a look of shock and disbelief when opening the package.

Last June we got a new CEO and we don’t know how he operates (our old CEO was a women and very cheap).

The price of the watch was very cheap. I’m hoping that the look on everyones face is priceless!

Do you think that my immediate supervisor and my lab manager will be fooled?

Any suggestions to make this prank work better?
