摘要:
Electromechanical timepiece fitted with a gear train including an hour hand and a minute hand for the current time display on the dial side of the timepiece. The timepiece is arranged to provide at least one additional piece of information relating to a magnitude of time, or to a non-time related piece of information. The timepiece further includes an additional indicator hand arranged to display the additional information, the additional indicator hand being mounted on the back cover side of the timepiece on an arbour of the gear train of the timepiece, so that the additional indicator hand and the hour hand and/or minute hand rotate at the same time and at the same angle, the hour hand and/or the minute hand being driven either to display the current time, or to enable the additional indicator hand to indicate the additional information.
