Hamilton Electric 500 Keychain

This is a rare Hamilton Consumer giveaway meant to help the customer see what was in his watch.  It has "Hamilton Worlds First Electric Watch" imbeded in plexiglass along with an index wheel, battery, contact & trip wire, and balance coil.  

It makes for a great conversation piece, and a great way to show others the unique parts found in your vintage Hamilton Electric Watch.  I have one on my keyring.
