The lack of a profit margin.

An authorized dealer will sell the watch to you for retail value, not wholesale value.

You can go ahead and resell those online as much as you want. I don't see how you'll turn a profit though.

Bah. Especially for a veblen good where they can trivially institute huge price swings. This site (https://millenarywatches.com/rolex-markup/) claims Rolex has a 40% margin.

I suppose it only works if you can make a deal with the authorized seller to split the online proceeds.

Good point. You could probably charge a premium for convenience, but would be hard to make it worth it.
