i just checked the serial on the minty certificate.
Its a 3.037 mio. # indicating the years 71/72 as period of case production.

In fact the watch was sold in 1973.

As this is a very clean first owner set i rate the dial as absolute original,
but have no clue what exactly the "Mark" is.
If you ever look for another home for it, do let me know.
