OK. Where's the polished steel version of the Rolex President then? The watchmakers who tend to work at the end of the scale don't make their primary designs in cheaper metals. Here, we see an apparently likely decision to make the exact same watch innards inside both cheaper and more premium metals.
Again, nothing particularly wrong with that. But for those whining for Platinum, they need to tell people they have the Platinum one. And once the marketplace fills(?) with polished steel or aluminum, that they had paid so much more for a more special edition would not be obvious.
You cherry picked one Rolex model. Rolex makes a lot of watches with steel, gold and platinum variants.
