Luxuary Smart Watches: What's the Point?

I recently started researching high-end/luxuary timepieces, for no particular reason since I probably never will have the money to comfortably spend $2000 on a watch, at least not in a forseeable future.

However, I did discover that TAG Heuer makes a smart watch collection. Do you know any other deluxe smartwatches?

This watch is more than double the price of the most expensive consumer smart watch. What are you paying for? Better sensors? Better software? Timekeeping? Suerly it's not just the brand...
Does anyone on here have this watch? How does it compare to, say, a Galaxy Watch for example?
