Define valuable? If its for the future, then your guess is as good as anybody.
More than a year ago, when the Pepsi GMT was released in white gold, everyone was scrambling for the older Pepsi GMT models, as many prophets from the rolex kingdom declared "no Pepsi in stainless steel from Rolex. never!"
Before last week, many were making calls to AD to list down their names for the arrival of a `Coke-Ceramic GMT stainless steel'.
So taken together, perhaps one can say a Coke 16710 been moving relatively slower in the preloved market for the past few months.
But today? Will you pay RM35k for a 16710 Pepsi, knowing that the new Pepsi retail is only a few thousand higher? Of course, there's the issue of availability, premium pricing, queue till the moon and back, but that's another story.
If its for getting one now, buy what you like and buy with wisdom
Personally, i feel proper papers, and even accessories is more `valuable' than bezel color. And condition of the watch itself-bracelet, untouched/polished. etc
Will you pay the same amount of money for a polished Pepsi (watch only) as compared to a minty Coke GMT complete with box, papers , tag?
