Sun Watch

These photos show the main difference between a Sun Watch and a "regular" Synchronar.  Normally the case has a metal bar going across the middle of the solar panels.  In the photo below, you see a plastic bar.  According to Roger, he had cases that either were missing the metal bar or that had metal bars that needed to be removed.  He took these cases and used them with a modified module that has a plastic bar where the metal would be.  These he called "Sun Watch."  See the article for more information on the Sun Watch..
