Honestly it baffled me too. Cellini is finely crafted. Size & styling makes it a great dress watch. Been said by all bros, it can make its mark in that crowded market segment.
In fact, portugese 7 days is so entrenched in the dress watch segment. Pricing right, variants of dial colours. Of course upscale Pp, lange brequet etc will always be there.
Many times I wanted to pull the trigger but the resale price put me off.
Like others, I too like to learn more....
