Abstract
There is disclosed a portable electronic device (1), particularly of the wristwatch type, comprising at least first and second analogue display members, a sensor (23, 52) powered to take measurements of a surrounding physical magnitude and a memory zone (26) for storing the measured physical magnitude values. The electronic circuits of the device are capable of operating the analogue display members, in an operating mode called the historic mode, such that at least one of them indicates the change in the stored value as a function of time opposite suitable graduations (8, 9, 33, 42, 51) of the device.
