Opened up the watch to see if 2500D is engraved or stamped somewhere. Didn't seem to find it. My 2500c was clearly visible but not on this. Is there a reason why?
That looks about right to me. I also made a small search online and that’s how they all look. Was your other movement on a display case? Maybe the add more to those?
On the D version it doesn’t say 2500D. When the serial number is horizontal on the balance bridge then you know is a D.
