This Oak cased barograph with bevelled glass and chart drawer to the base, signed by Negretti and Zambra has been fitted with a monthly rotating clock drum. The beauty of this movement is that the chart readings are compressed enabling a whole months’ barometric pressure to be displayed on a single, standard-sized chart. This barograph is in excellent condition and would be ideal for display with little attention as the chart only needs to be changed 12 times a year!

Rare monthly Barograph
