The swap was easy/quick and I'm happy with the change. The characteristics of this watch change remarkably with the dial options. The black has a bit of a vintage look while adding some apparent depth and heft, whereas the sportier white is tops in natural light. The printed elements on white also look a bit more distinctive (the splash of red basically disappears on the black) and the dial is slightly more legible overall, but they both read fine for me.
In isolation, I somewhat prefer the white option, but this wears a bit better on my wrist. I'd be tempted to swap back (of course I kept the original dial) if I lived in a more consistently sunny place. Just thought I'd share my thoughts as this question is inevitable for those considering a stainless Daytona.
