Altitude measurement device including an atmospheric pressure sensor arranged to be compressed or to expand in a rectilinear direction as a function of the atmospheric pressure to be measured which increases or decreases, wherein the movements of deformation of the atmospheric pressure sensor are transformed, via a transmission system, into a pivoting motion, in a plane perpendicular to the rectilinear direction of deformation of the atmospheric pressure sensor, of an activation system which drives the pivoting of an indicator hand, wherein the indicator hand moves over a graduated circular scale, wherein the atmospheric pressure sensor is arranged to be able to be moved in one direction or in the opposite direction depending on the rectilinear direction of deformation thereof relative to the other components of the altitude measurement device, wherein the atmospheric pressure sensor is mounted on a seat which is fixed in a support, which forms a case with a cover.

A barometer clock includes a clock face, a clock mechanism, and a spindle located in the face and driven by the mechanism. A barometer mechanism includes a barometric sensor, drive means and drive shaft and a plurality of display members located behind the clock face, each member engaged to the drive shaft by a gear mechanism and rotatable by the shaft in response to a signal by the barometric sensor. The clock face includes an aperture, each display member being rotatable between a respective visible location wherein the display member may be observed through the aperture and a hidden location wherein the display member is concealed by the clock face. The gear mechanisms are adapted to successively move the display members between hidden and visible locations as the drive shaft rotates to provide a display characteristic of weather conditions associated with pressure conditions measured by the barometric sensor.
