Tritium Asymmetrical dials; was it just Speedmasters or also other models?

[Horologist]

I recently was looking at some of the older Speedmaster Omega models and noticed that their Tritium dials came out in 3 variations as can be seen in the following image ( image is not mine but borrowed from watchfind) The literature I found on this was that the second image showing the asymmetrical ( and mis-lined inscription of the) "T" font was a transition dial during the Swiss laws mandating that Tritium lume was to be labeled on the dial even on pre existing dials which did not have it labelled prior to the mandate around 1964 I found this very fascinating as it was the first time I had noticed this. . My mind could not help wonder if Seamaster and Constellation dials also came out with transition dials. Has anyone ever seen this on other models or have one you can show?. It is a very interesting topic which I could not find any literature on.

I’ve seen it in on other models from 1963-64 so yes it happened elsewhere too.
