The watch is able simultaneously to display the current time and the parking time already elapsed. The output of a frequency divider (3), delivering one pulse per minute, is connected to the input of the first stage (4) of a divider, with a division factor of 15. The output of the first stage (4) is connected to the input of a second stage (5), with a division factor of 4. The stage (5) is connected to a decoder (6) whose outputs are connected to a parking time display unit (7). The latter has four surfaces which can be activated individually one after the other and it may be combined into a unit indicating the current time. <IMAGE>
