I came across a press release photo from 1955 showing a non-working prototype of an analog solar powered watch by Elgin. I knew that this large and famous Illinois watch company had done some of the earliest work in trying to develop a battery powered watch so I was not surprised to learn that they were thinking of solar electric power. This is the earliest reference I have found to someone trying to develop a solar powered wristwatch. The only thing I did not know was how far they had gotten in making a working model. Had they developed a solar watch more than a decade before the Synchronar?
I published a letter in the National Association of Watch and Clock Collectors Bulletin (Volume 51/1 No. 378, February 2009) with a photo of the watch and asking Elgin experts to tell me what they knew about this project. All the Elgin experts I have heard from suggest that the non-working prototype was as far as Elgin got. It is a good looking watch but the technology was just not developed until Roger Riehl worked on it. There is no evidence yet that anyone actully built a solar watch before he did. I will keep the DWF posted if I discover more about the Elgin watch.
(Sorry, I tried to post a copy of the letter, but I could not figure out the the Image Shack software)
