Asi mate don;t try hard - If its not working 4U then stick 2 ->
what you like & know the best. You already told many of times that Panerai is what rocks your world that simply 4 U there is no substitute so why would you go & try to change that.
I say you enjoy what you enjoy & that's simply it. There is a time of change for everyone so is for you and until then you shouldn't feel like you need to try anything else.
Don't worry I think there is no conspiracy theory for change or trying to go diversity route imposed ;-) I think it's just that some have overgrown only Panerai collecting & ready to move on to appreciate other brands that currently offer to them something more in sense of desire/quality/excitement/value/ETC
