Hi, I have no other photos nor won't be able to test it with UV. Thoughts please?

Do you have it with you?

Go in a dark room. Flash a torch on it for 30 sec. Turn lights off.

if it glows more than 3-5 mins => Luminova
If less or very little => tritium. (what glows is the residual zinc sulphide)

Just visually, looks like a Luminova relumed, but happy to be proved wrong

Given the quality of some of the work nowadays it’s impossible to say from that photo.

All you can be confident of from the pictures provided is that’s it’s either original or a good relume.

V difficult to tell as said above, but from the photos shown, the lume looks fresher than the dial.

No, I do not have it with me, I am looking for a second opinion before making a purchase.
A seller says it is around 1968, replaced during the service (no paperwork to back up this statement), tho I do not understand why would anyone want to replace the dial in such a nice condition.

The dial surface is too grainy for me. Relumed for sure. The scratched in numeral and lines on the back look like a re - printer's work....

The place of purchase mentioned in the product description is a somewhat famous watch store in Japan.

I would say relume. While they don't always have the pin holes I would be pretty suspicious of any dial that doesn't have those.

Except that good relumers will produce the pin holes if you ask them.

Agree a good relumer would do that.

Since I know what my watchmaker can do with different kind of lume I'm in the dark telling people from pictures if it's a relume or not.

As other mentioned already… impossible to tell nowadays just from pics.

But what I can tell is, that anybody has had some fun playing tic-tac-toe on the back of the dial 😉

Just from my guts feeling Iam on the relumed side.
