I agree with my colleagues on the forum completely.
The Pepsi GMT is a great watch. Put your name on the list and wait. Patience is a Virtue!
One of these days, ( maybe years) you are going to get that watch at the right price and you will really enjoy it. Buying at 3x over retail is a hazardous move. Certainly, in time the prices might drop. You may come to resent the timepiece and get no joy from it whatever. Hang in there.

I bought this GMT new back in November of 1986. It is no longer the watch I wear the most, but I still love it!
