My *Bay purchase arrived! It's definitely better than the auction made it seem. The face is almost perfect, the plating on the case looks good, and the acrylic crystal is barely scuffed. It's on a no-name "USA" stretch band that I think works well with it.
The AS/ST 1950 movement wound, set and runs so quietly I can barely hear it even when I wedge the thing in my ear.
If I'm reading the Ranfft page right, this movement is from around 1965 or so, right?
For what it's worth, the case was made by Louis Lang, SA.
I'm happy. Especially for $16, shipped to my door.
