Loads looking wrong here to me......walk away. Dial looks much younger. Speedmaster 'S' is a much newer version. Wonky "T"s looked added. The applied omega symbol is not straight .......etc etc..
The T Swiss Made T looks very strange but often times the curved edge of the crystal distorts this inscription. Need to see it from other angles or dial removed from the case. The step is also difficult to see at some picture angles. It's also possible that the dial is a old service replacement and has no step.
... short indices, not long. Not wide t swiss made t, Omega and Speedmaster writing is not right: I woudn't want that dial for my -68 transitional (the insert too)
