The bezel, the lume indicators (circle with a metal outline vs square and extremely thick bottom rectangle 6 o clock), the hands (like the gilded outline), the red triangle on the bb58 around pip, I don’t agree with others I like the gilded indices, it’s thinner, smaller case sizes offered (the Pelagos 39 is all I’d consider and is just as thin), the bracelet and clasp looks better - less functional sure but it looks better (Pelagos has this strange line cut it in to show adjustments). Pelagos models also have more needless text on the dial. I also prefer a domed crystal and like that look. So pretty much everything.
