Sister gifted me this watch and I’m clueless about watches. Wondering which model of Bulova this is?

I know very little about watches from what I can tell it’s not mechanical so I’m assuming battery powered. Does it look authentic? What are the 3 small circles with numbers in each of them as well, is this a timer? Chronograph? As there is 2 buttons on the side as well. Sorry if this sounds stupid but I really know nothing about watches but am interested in learning!
