All credit goes to Cheryl for spotting this. I’m not sure we noticed this 3 years ago during our first visit to Sun Studio in Memphis. We had recently watched an episode of Auction Kings that featured a similar spy watch. Honestly I thought she was joking when she kept telling me to look at the display case behind me. Since I’m not aware of how long this piece has been at Sun Studio. I couldn’t tell you if it is the one that was purchased from the auction house featured in that television program. I’d venture a guess that the Sun Studio spy watch has been there for some time.
From what I can see in my pictures I think this spy watch is a Minifon model P55 S. You can see Geiss-America Chicago 45 ILL on the label. From my reading on one website I think Geiss-America was just an importer of this product not the manufacturer.
