Abstract: Provided is a communication system that includes an electronic timepiece and a communication apparatus, in which, when the electronic-timepiece communication unit demands a communication connection to the communication apparatus, the communication-apparatus control unit inquires whether or not the electronic timepiece is included in the connection approval list that is stored in the communication-apparatus storage unit, in which, in a case where the electronic timepiece is included in the connection approval list, the communication-apparatus communication unit establishes a communication connection to the electronic timepiece and performs data communication through which at least clock time data is sent to the electronic timepiece, and in which, in a case where the electronic timepiece is not included in the connection approval list, the communication-apparatus communication unit does not establish the communication connection to the electronic timepiece.

Abstract: An electronic timepiece includes a display unit, an altitude measurement unit that measures an altitude, a RAM that stores an ascent integrated altitude plan value which is a plan value of an ascent integrated altitude value, and a CPU that calculates the ascent integrated altitude value obtained by integrating an altitude variation amount during an ascent, based on an altitude measured by the altitude measurement unit, that calculates an ascent achievement ratio which is an achievement ratio of the ascent integrated altitude value with respect to the ascent integrated altitude plan value, and that causes the display unit to display the ascent achievement ratio.
