If you think it's too big for you, then you probably won't wear it. Try to think about what excites you about that watch, what outfit would you wear it with? To what event? If the most exciting thing about the watch is the fact that it's finally here, then maybe you'd get more enjoyment from buying something that holds value to you in the moment.
You could always get a cheap beater of a similar size to see if you like the fit
Wait so now I'm in trouble for not being on my phone? Make up your mind! /s
