First Watch Question: Omega Speedmaster Moonphase Blue

Hey everyone, I’m planning to buy my first watch, and after going through all the options, I’ve narrowed it down to the Omega Speedmaster Moonphase in blue.

It comes with a blue leather strap that I really like, but I’m considering switching it to a steel bracelet at the boutique. I genuinely love both options and can’t decide. What do you guys think? I’d love to hear your opinions!

I have two pictures with the first picture of me wearing the watch with the original blue leather strap and also found a picture online with another gentleman wearing the same watch with the steel bracelet. Our skin tone is pretty close.
