So is a mechanical watch at all for about 99.7% of the population. With all things relative- the co-axial escapement is subjectively "good" simply because it is "different" than what other mechanical watches use, and therefore it is "exclusive."
There's nothing better about Rolex (for example) except for exclusivity (again- with all things being relative). People choose different brands for a variety of different reasons.

luxury items in of themselves are solutions to problems that don't have to exist? Same thing really applies to cost:benefit- when it comes to luxury items this doesn't even begin to be a big part of the equation.
