Hi
@shah@123
Your research is pretty much spot on, although the date could be end of 50s or very early 60s.
If you are asking if the rail track should be round, then the answer is yes.
if you’ve seen others that aren’t I suspect they were distorted pics.
these dials are notorious for having the rail track repainted - you will need hi res pics to determine if this is the case (from the pics provided the minute marks on the rail track look uneven)
in general, the case isn’t bad but the dial is showing signs of degradation and the movt looks very tired.
Edit: I should have added that it has an incorrect crown of course.
whether it is worth buying depends on the price and the condition of the dial.
Hope that helps
