Omega Suveran 2400 - relumed or not?

With the shrinking options of watches that can be considered both vintage and affordable, I've been looking at these Swedish market Suveran's and have found a seller who claims the dial is all original Radium (not tritium).

To my eyes, for a watch that's nearly 80 years old, it looks like a relume (but a very good and even one) but I am not an expert and speak purely from the point of view of skepticism.

I am told that it was checked under a Geiger counter and confirmed as being radium and there is a UV shot that has been provided (which looks consistent across).

To be fair, the dial looks really good, though it is high priced (USD 2500 equivalent and without an extract).

Love to hear from you fine folk (click to view super high res).

It's all original IMO and in good conditions

I think the lume looks ok for me, dial is in an exceptional condition. Case looks newly polished and have lost some mass from original but still very good.

Price is top dollars for a Suverän and I would have expected a black dial or maybe a centrum second or something else more desireable for that money. But you rarely seen them this good so its not crazy.
