The early 212s did have a manual wind seagull movement, Austin. However, it has a display caseback and the manual wind movement is visually completely wrong compared to the gen auto movement (obviously). The early manual powered models had a more correct dial with the minute tick marks "facing" outward instead of inward. Unfortunately, that model had a less correct CG, although it didn't have the "reg. tm." engraving on it.
Having said that, my favorite Panerai is my 196. The only things that really need to be addressed are the lume color is a bit too green (plain C3, I believe), the hour marker at 6 is a bit too long and the CG needs the lever mod done. The date font may be a *bit* too thin, but it's not bad.
