Neing a talking piece is not the main goal of it, just a consequence or a secondary one.
Again as dreamer8 and Foversta said, there is a list of work of Mr Haldimann beofre this one which gives even more sense. It brings a lot of impressions for the guy who wears it, intellectual pleasure and fun, other sensations that just looking at time or mechanics; wind up, weight, sound (and when you look at it you see yourself, I find that detail really brillant).
For sure it is a controversial piece (maybe the most controversial of all), but the more a majority hates it, the more it get stronger for those who loves it imho.
After wearing it and looking at reactions, I love it more and more
cheers
