Rolex OysterQuartz Presidential

[BigBlue1]

Hi there.
My name is John.
34 years young and have started to look at Rolex’s.
I am in the market for a nice affordable time piece.
I recently stumbled across this completed auction
https://m.ebay.com/itm/263464143702#vi__app-cvip-panel


The watch looks very cool. Doesn’t look like the dial is original to the watch. Seems to be solid 18k including the band.
Never heard of the Oysterquartz and wasn’t even aware they made a quartz.

Is this a decent price one can expect to pay?
Does this watch run on Battery?
Excuse me but my knowledge is very limited.

Any help is much appreciated and welcomed.

Thank you in advance for your reply’s.
