These odd cases seem to have turned up mostly out of luck, but possibly from far too many hours of hopeless searching for that horological mythical beast - the affordable Pulsar.
Below is a photo of the inside of the case, front and back. Note the "Star Watch Case Company" logo. The case is quite small - only 25mm wide by 35mm tall by about 6mm thick. It makes you wonder if they had a module design in mind that would actually fit the space or if this case was intended as purely an aestheic / conceptual model.
I was hoping that this example was hand fabricated by Mr. Jean Wuischpard himself, but I have no idea if that is the case.
On a tangential note, those of you who follow this forum may have noted that the P1 case in the photos above has been restored since its last appearance. There are a few tiny areas that could use some additional help beyond my expertise so last week I gave Mr. Peter Wuischpard a call (Jean's son). He picked up the phone and we had a nice little chat. He was familiar with most of the Pulsar models and was a bit surprised to learn of the NiAg P1s. He asked if the time screen was ruby and when I told him it was acrylic he said "Yep, they really cut corners on a few of those models."
