We know that the 7SXX ‘A’ movement has been modified to a newer ‘B’ version. I managed to borrow a Seiko 5 with 7S36B movement and took a picture of it. I have also taken pictures of my 7S35A and 6R15A movements for comparison.  
Please click on any thumb to see a larger image.




I am not a watchmaker so I won’t comment on them but anyone who wants to make use of these pictures for posting their comments on any forum or blog, please feel free to use them (provided you describe what these movements really are instead of what you want them to be).
Also, here’s a 6R15A and 7S35A comparison shot that I took previously.
