This guy is selling a Speedy with 321 movement. The movement, however, is considerably older than even the earlier pre-professional Speedys. The dial is obviously wrong, lacking "T"-labels.
He is also not keen to answer questions. Notably, he doesnt want to tell me which Reference-No the watch is. The watch seems to be assembled from Speedy-parts of different eras.
