BUY her the CHINEESE COPY of the $1200 watch.    You have to put some more thought into these problems.  Save more $$ for a pinny. 

OR

Tell her you are going around the corner a "few nights a week" to a nice young lady's house who has a decent pinball collection.Then mention that if you had a bigger collection, you might not have to go around to the nice lady's house. 
NOW, at this stage, she will either kick u in the balls really hard, or she might get out the magnifying glass and look closely at that $20 Chineese copy of the $1200 Rolex.

With most people u get what u negotiate, not what u demand. BUT when it comes to the wife, sometimes u get only what u demand, then do a deal and give her something she wants.
Example - My wife wanted a Second 55 inch LG 3D TV today for the bedroom cause I bought another pinball last week which will come next week. Its a WIN WIN here cause we both get to use the new TV in the bedroom and I get the new Pinball. Sometimes u have to let them think they are going to win.
