A great collector's item.  

This Howard Miller clock runs on 1 x c size battery. It comes with a photocopy of the original instructions. 

It features multiple world time zones, however I can only get the local time function working. This clock is an original piece from the 1970s, and its excellent condition makes it a must-have for any clock enthusiast or vintage collector.

See video of working above. Speed can be adjusted, but I haven't altered anything or checked the speed. I have only put a battery in to check if it is working as you can see it is, being sold as is. 

There is some wear/tear to the silver finish on the front, and general wear due from age/use.

It is also missing the battery cover at the back

Please view photos and video for your personal assessment.
