Dial Finish Differences in Blue 15400 vs 15450

[Lo0o0o0n]

Hey all!

Was just wondering is there are any dial finish differences in the blue 15400 and 15450 (and hell while we're at it, the 15500 as well, although I do already quite clearly see differences in finishes there)

Personally, I own the 15450 blue dial and it seems to shine and shimmer more than the 15400s I see online. I also seem to see more of the shine and shimmer in the blue 15450s online as well, not so much in the 15400s. For those that has had the privilege of holding both side by side, do you see the light reflect off them differently?

Thanks all!
