Hard to say anything definite about the watch without better close-ups, but it doesn't look like a redial to me as the script is very fine and that's pretty dificult to reproduce on a textured dial. There is some issue with the hands (I'd say that they have been relumed), and the dial has probably had luminous materiale by the markers once - I'm going out on a limb here and guessing that the dial has most likely been cleaned at some point (losing the radium plots in the process), but not redialed.
