In general I don't like chronos and prefer a date window but those aren't dealbreakers. I usually go by looks first and then look into the movement and other details.
The RO intrigues me, but when I put it on, it didn't speak to me. Maybe I need to try it again? I actually like the 15305 but its out of my price range and my girlfriend hates it. I like the looks of PP and ALS (obviously) but again out of my price range.
