If you're referring to Android Wear's need to pair with a phone, then they also do that. Once paired, your watch can still tell time without the phone.
That being said, and while I don't agree with a 10k watch that does the same as their 500 one, this is gold, so the material cost MIGHT justify it (again, I'm not sure if it does, I'm no expert). Not something I would buy, but I'm sure a lot of people out there don't know what to do with their easily-obtained (in my experience, people with this kind of cash to burn on a whim don't really earn it and don't really have a hard time getting it, but again, not all of them... some do work hard to get rich) will be happy to buy one.
