I think we should talk about "service" dials, a thing I don't think exists in UG world. 😀
Well, it’s one of these later generic (but UG original) dials. No dash in Tri Compax, lume plots and numbers, one size only (32mm the dial plate). Made by UG probably in the 60s.
There is enough info about this type of dial (for example in the Tri-Compax thread here on OF:https://omegaforums.net/threads/ug-...ce-guide-read-entire-thread.48137/post-577435 ) .
So an original replacement dial. Interesting to see that double signed imho.
