Apple has worked diligently for years to occupy the position they're in today. At this point they have the power to do as they please and rightfully so.
When you're ready to upgrade your watch you simply buy the newest model.
What you are describing is an incredibly stupid business model. If Apple really did business this way, then it would quickly fall from the richest corporation ever into bankruptcy.
Remember Apple is in the fashion business now, think fashion not tech and you'll have no problem.
You may convince yourself that Apple is now in the business of selling decoration. Somehow, I think that you overlooked the fact that Apple does not sell cuff links and tie clasps. It does not sell necklaces, ear rings, and wedding bands.
It sells [will sell, actually] smart watches. The things that makes a watch jewelry are the precious metals and jewels used to manufacture them. There are no jewels in any model Watch. The most popular model of the device is expected to be the Sport, which is constructed of aluminum. Aluminum is not a precious metal.
The Watch is a tech device. The thing that separates this tech device from Apple's other tech device is that it will sell at margins higher than any of Apple's other tech devices. I estimate the Sport to have a margin of at least 100%. The SS models are also manufactured using non-precious metals. They are tech devices that will sell at substantially higher margins than the Sport.
The Edition has a gold case which qualifies it as jewelry. With a retail price as high as $17,000, it is the most expensive consumer device in Apple's history. Depending on the model, the Edition's unit profit margin is $9,000-$12,000 (300%-400%).
It was stated in an earlier post that Apple will not sacrifice iPhone sales with Watch sales. This is laughable. The iPhone sells on very slim margins with most sales subsidized by a cellular provider. Every model of the Watch is a license to mint money and will have no subsidy.
So, keep telling yourself that Apple has abandoned tech for the fashion business.
