How many glued watches match the cost of a single properly assembled product? How many "great customer experiences" taking/shipping it back for a replacement of another glued watch would match a solid built product which would require none?
Again, your questions you have listed above have no relevance to the current situation. Furthermore, you seem to be sidetracked off the main point, which is Apple has already addressed and continues to address the issue at hand with some of the first generation Apple Watches experiencing issues. They set up a process where the watch will be repaired for free at no expense to the customer and they have the option of going to an Apple store or sending it in for repair.
Which, no one here knows the ratio of watches that have experienced the defect compared to the watches that have had no issues with the adhesive and work as normal.
But in the end, all that matters, is Apple Addressed the issue by creating a plan for the consumer and not every watch has had this issue, it's a plan devised for those who do experience this, they now have options.
I would rather put my faith in the company that still makes a great product and yet even if it does have an issue, I can feel comforted knowing they are going to resolve it. Again, what other company will provide you this type of customer service.
Lastly, Apple isn't perfect and nor other companies that have made mistakes with their hardware as well. Apple still makes a great product, but what makes the product great is the customer service behind it. That's the whole intent behind the product with Apple and their customer service.
