Hi Pschcologist
I have some NOS Savants here. I cant give you a huge amount of information but I know from the packaging that they were either made or distributed by commodore. The also produced the trilite which was some sort of coating that lit up at night(these are the models I have(they no longer glow), I think the company may have been Savant and these were a product of Micro display systems inc.(this came from an advert somewhere else on the net) in Dallas, whether the modules were made there I cant tell for certain. One of the watches I have is at my site here:

I hope this gives you enough of a lead to find out more info, if you do find out more let me know so I can add it to my site
kind regards
Adam
