Portable electronic device with analog display rate of climb indicator

A portable electronic device comprising:

• (a) a case containing a dial;
• (b) at least two analog display members, namely, first and second analog display members, disposed above the dial;
• (c) motor means controlling at least two analog display members disposed above the dial;
• (d) means for determining value of physical magnitude related to altitude at a given instant;
• (e) electronic circuits comprising
• i. a time base;
• ii. means for processing value of physical magnitude related to altitude at a given instant;
• and
• iii. means for storing one or several of determined or processed values of physical magnitude, wherein the processing means are arranged to produce first control signals for said motor means based on the determined values of physical magnitude, for effecting, in a rate of climb mode, a display representing an instantaneous rate of change of altitude by the first analog display member and a mean rate of change of altitude over a predetermined interval of time by the second analog display member, wherein position of the first analog display member relative to the second analog display member provides a qualitative indication in terms of acceleration or deceleration;
• wherein the electronic circuits further comprise
• iv. a timepiece movement, and wherein the electronic device has a time mode of operation in which the electronic circuits are arranged to produce second electrical signals for the motor means to contact the first analog display member and the second analog display member in such a manner that the first analog display member and the second analog display member display current time.
