The single AA battery operated quartz movement requires no winding and is more accurate than key-wound movements. The conventional ink nib and messy inkbottle are replaced by a felt tip pen, which lasts 6 to 9 months.
This barograph is furnished with a one-year supply of weekly charts, AA battery, and one felt tip pen and dampening fluid.
