Barigo Barograph C/W Mahogany Case

Mechanical barographs have a solid rotating brass drum that is driven by a quartz battery movement to rotate the drum once a week. A felt tip pen at the end of the writing arm shows changes in the air pressure on a paper diagram that is wrapped around the drum. A mechanical barometer movement with eight round diaphragms (four in the case of the model 2018) measures variation in the air pressure and transfers it very precisely through a system of mechanical levers to the writing arm. The high-quality mahogany case is polished several times and treated with a special high-gloss lacquer.  All barographs come with a supply of charts and felt tip pens for one year.
