Hi,
Buying at list price I would pick the 5712/1A.
If I had the choice of gold or steel at the same price I would take the gold version.
Choosing between the white or pink gold I would have a hard time. The pink gold with its borwn dial is gorgeous (to my eyes).
My choice in the long run would be 5712/1A + 5712R!
Cheers
