1A108 and the 1A110 Round Metal Case

The Auxiliary Movement clocks will run continuously through current interruptions as long as two hours! The self-starting, synchronous movement clocks have a pendant reset eliminating any necessity of removing the clock from the wall, once it is installed.
 

That ticking you hear after you unplug this clock isn't in your head.  This model features an auxilary motor that takes over in case of power failure.  All of these had a "Statuary Bronze finish".  The 1A108 has a 12-ince case and an 8-inch dial.  The 1A110 has a 14-inch case and 12-inch dial.
