This watch has a lot of good lessons.
the big red flag, apart from the white markers, incorrect bezel, service pushers - is the miss matched colours in the movement.
I would be amazed if this watch got an extract - if and when they start doing them again.
almost certainly this watch was built up from parts from many different sources.
that said, everything has a value, even this, and the end result will be a wearable watch that will give pleasure.
the trick will be resist the temptation to correct it, one little piece at a time.
that road is the way to madness….
