This German made barograph is housed in a mahogany
case with glass sides and a polished brass handle for
easy access. The single AA battery operated quartz movement
requires no winding and is more accurate than key-wound movements.
The barograph readings are marked with a felt tip pen that lasts
6 to 9 months. It is furnished with a one-year supply of weekly
charts, AA battery, and one felt tip pen.
