G-Shock anyone?

There is a correlation between price and exclusivity, but it is not linear and has a poor correlation coefficient.

Some labels, say Rolex Oyster watches, are quite pricey but worn on just about every business arm in China. Not exclusive.

Even an item that is rarely seen except in marketing communications can be considered to be not exclusive.

For example, a Cartier Rotonde de Cartier Astrotourbillon costs $116,195. Super pricey, yes, and rarely spotted. But they appear in many ads for Cartier and this erodes any genuine exclusivity.

Rarity, the chief sign of genuine exclusivity, is made possible by both limited supply and limited marketing visibility. Price is then just an indicator of quality, the greed of the supply chain, or the stupidity of the consumer, and sometimes all of these.
