"I was in the Rolex store in Waikiki last night. EVERYTHING in there was geared toward a rich Chinese (my wife is Chinese, but far from rich). Gaudy colors and bezels galore. Not a single Diver/GMT/explorer/etc to be found. I was wearing a Tudor, and my wife, a Daytona. I think we had the nicest stuff in the store."
I would respectfully assert that while demographics may have HISTORICALLY had something to do with the product mix there, there is a "shortage" of the watches you reference worldwide as per Hoodinkees, Worn & wound as well as other PF like watch online resources.
The go to Rolex place in KC since Fall has had exactly 0 stainless Submariners, 0 stainless GMTs and scant few Explorers or even stainless Daytonas.
The other Rolex store in town was rumored to have been allotted two of the the New Stainless Pepsi's GMT IIs for 2018. It took a meeting of the owners with the sales staff to determine which long time seven figure customers were going to get the opportunity to buy the watch at retail-9250 +tax

My watch geek buddy was willing to put down a 10% deposit when the model was first announced fully understanding that it could be years before he could buy one. They declined to accept his deposit because as a 2 Rolex, 1 Panerari 1 Grand Seiko watch owner, he was never going to be in play. They were not going to price gouge, they simply were only going to sell that watch to customers who had, over their lifetime, spent so much more at the store.
