Abstract

A portable electronic device () is described, in particular of bracelet watch type, comprising at least first and second display members (and), means () for making measurements of a physical magnitude related to the value of the altitude and a memory zone () for storing the measured values of the physical magnitude. The electronic circuits () of the device are adapted to control the analog display members, in one mode of operation called the rate of climb mode, so that a first display member () indicates the instantaneous rate of change of altitude and the second display member () indicates the value of a mean rate of change of altitude against appropriate graduations () of the device. Such a device finds its principle application in the field of aeronautical sports.
