Hello!
That's right, REP PAM029 from NOOB, really superrep.
In order to properly understand everything, you should understand a little about gen PAM029.
The PAM029 was launched immediately with the A series and featured a T dial, and already in the C series it was replaced by PAM063.
Later, as with PAM028, PAM029 was reissued as part of a special series, and this series was M.
In fact, there can be 3 types of dial: PAM029 T (AB), PAM029 L (AB, but service), and PAM029 L (M series).
Formally, the M series iscompletely new model. New case, new dial and more.
This is the essence of the differences you mentioned.
And yes, PAM023 has no dial texture at all, it's a different model
