The watch itself does not work for a very long time. The musical accompaniment is a little annoying, and on weekends, when you want to sleep it off, a little more. There is not much benefit from this chapel in modern society, given that almost everyone has phones, and some also have watches / bracelets. As for me, it's more like an annoying factor. It would be better to spend money on a sports ground there or something else.
It's worth it and it's worth it. What's the use of it? The same as from any obscure monument. It seems to be there, but why is unclear. Do you have a watch? It's cool! What for? It's also unclear when everyone has mobile phones. But if there is, let it be. It doesn't bother, maybe it means something to someone...
