Guys, thanks for your replies and advice,
Bottom line, i think the consensus is, dont waste money on somethng that is essentially never going to be a gen, I fix the dial - the bezel bothers me, I fix the bezel - the crown bothers me and so on!!!
I saw docblackrocks pics of his upo with double AR and gen rubber strap, I think thats what i'll do. My intention is to buy the gen chrono, and have skinny wrists so I will no doubt use the gen rubber strap on my gen chrono when I buy it at the end of the year, so nothing will be wasted.
..... The bloody lume on the upo does bother me though!!!!! Aaaaargh!
