I have the dial off the watch to check. well the marker at 6 is OBvisously thicker broader.
the lume is same, just the surrounding thicker.
as seen in gen, I don't think I seen it different yet.
If you put it under light , the reflection of the surrounding will make it very easy to tell.
if I know how to reassemble those marker. I will exchange the 9 on wm9 to mine new tc. Haha
by the way, one more thin I notice , the 6 is always whiter uncharged lume then the rest of the dial.... happen in both dial too
