This is a stunning gold watch that you can set once and forget, well almost. I believe you have to turn on/off daylight savings time. But the calendar sets to the correct day even on leap year. And with the atomic radio sync it seems to be good to half a second at any given point in time. Sapphire crystal is a must! I have another Citizen with a sapphire crystal with zero scratches even after knocking the crystal numerous times against sharp edges. The downside? It's heavy. The chronograph minutes sub dial does not have hash marks. It can be a bit complicated to set up the perpetual calendar, although mine arrive with the correct date and time. It's a bit complicated for a formal watch. But I don't mind that, I'll still wear this watch on formal occasions. I intend to get a dark brown alligator leather strap as another option. There is a titanium model PCAT and that's worth considering (my other Citizen is titanium).
