This is just what I needed to keep my automatics running.  It has 3 or 4 intermittent settings, so you can adjust it depending on the watches.  It sits unobtrusively on my dresser and hums quietly along at 3 hour intervals, for 30 minutes at a time.  I had one from Brookstone years ago that didn't work at all, I think because the watch mounted almost flat on its back.  I'd buy another Diplomat and would recommend it to anyone with automatics that you don't wear a lot.
