[Cartier Ballon Blue] First Cartier watch as a present for going through cancer treatments

I bought myself a 28MM Cartier Ballon Blue as a present for fighting breast cancer all of 2024, right after my 40th birthday! This is also my birthday present for turning 41 later this month, a day I wasn’t sure I’d see when I was diagnosed last year.

I am a bit bummed that 28MM does not come with automatic movement. Should I exchange for 33MM or does 28MM look good on my wrist?

Thank you all! 💗
