Little Diffraction Gratings!
I love how the grooves in the dial markers on this style of Grand Seiko watch act as diffraction gratings, splitting the colors of sunlight apart. You get not only crazy reflections and sparkles of light, but also rainbow colors, in the right light.

Wtf what a nice dial brother amazing piece you got there
Grand Seiko never disappoints tbh
They don't do it on everything - but agree - it looks awesome when they do!
I've found the Heritage line generally has it (as does my Seiko LX, a 6k Seiko diver made by GS) while the Elegant line and Evo9 line usually don't have it.
SNR043 Has the light refraction:
Thin dress series Ryusendo - Nope! BUT.. the reflectivity of indices is maximized by using extra facets, so all good!
EDIT - posted this a while ago but was I banned all last week, so trying again!
