The case back has #2446 printed inside, but that does not match with the appearance of the watch case and with the crystal installed. The 2446 case has rounded, convex sides while this particular watch's sides are flat, and the 2446 uses a smaller crystal (A1254EW).
If this is indeed a case #2528 with a #2446 case back, this would make my watch a factory Spaceview (G). If this is instead a case #2600 which is identical and uses the same exact crystal (1270AWS) as the #2528, this model would be a conversion.
After closer inspection, it looks like the reflector is genuine and installed properly...so I feel I should only have the wrong case-back.
Would love some input as I'm trying to figure out the story of my watch.
Thanks for sharing your thoughts.
