it is obvious that this -69st had some replacements:
- the bezel is a recent version (version 2004 it seems to me),
- if the hands are luminous then they have luminova and not tritium,
- the tritum of the indexes has been removed, perhaps it was degrading too much.
this is indeed a correct stepped dial for the -69st,
- the 1162/575 bracelet is not original but it is vintage. it looks a lot like the 1116/575 that can sometimes be found on -69st.
many speedmasters have had parts replaced as they weren't considered jewelry like Rolexes of the time. so they were worn a lot and were exposed to life. can we blame their previous owners for wanting to make them cleaner? Finding period pieces in good condition takes a lot of time and a lot of money. apart from the collectors that we are, most people think that we quibble about the font used, the presence of a dot in such a place...
everyone has their requirements, the important thing is to be aware of them and to be happy with the object you have.
