Maybe wear it a little looser?
It does look like the innermost piece of metal in the buckle can be bent somewhat to reshape it. However, I couldn't tell for sure without examining it in person.
IIRC, wasn't it expected to cut the rubber straps once purchased, to get a better fit on the owner? That would also change the angle of that innermost metal piece, depending on where you cut the strap. Or am I thinking of some other watch?
