.......my personal point of view is to keep the 5970 white gold ( as well as Rose)..
Remember all the main " heavy" collectors are more focalized in 1. PLATINUM 2. WHITE GOLD 3. ONLY vintage out of productionn watches in Yellow Gold .
In few words to sell or bartering a white gold PP 5970 is a big mistake now.
It is beautiful and performed 70% of his value in the last 7 months .....
You are very well informed : one year only production.in few words SOLD OUT ( like 5070P, my dream)
But I could be wrong ........regards and have a nice weekend , Walter
