just bought a new superman (4R36)...it's my first seiko, and I have some Qs about adjusting the day/date

1. About the day, i've notice there's alot of display options from, redblock, Mon, I, Tues, II, Wed, III, etc...
Q: what does the roman numeric means?

2. About adjusting the time/day/date.
I've tried to adjust accordingly, but I've notice when i adjusted past 12am, the date rolls to next date (which is normal), BUT the day doesn't, but when I keep continue adjust the time forward, the day switch to next day when time is 1am
Q: is it normal or am I did something wrong earlier and F up?

After some curiosity & worry, I read the manual, and it says should not adjust the time/day/date between 9pm and 4am, and I can't recalled if i accidentally did that..

appreciate sifus out there can guide me up...

Date like 10,12,14 changes after 12am

but day like Mon,Tue,Wed, etc changes after 1am

So it consider as normal case?

I expect Date & Day will change together once time reaches 12am...logically.

won fb bid for 699...super steal, although it's not the color that i've wanted (blue)
