A wonderful way to keep records of barometric pressure readings is with the German- made Classic Barograph which is housed in a rich mahogany case with glass sides and a polished 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 on paper charts with a felt tip pen that lasts 6-9 months.
