ORDERED MULTICHRONOGRAPHIC TIME SEQUENCES

Ordered units and methods of multichronographic time sequences are provided which are operable to up count and down count such time sequences by using a single control element for each such type of count. These single control elements are manipulated in a unique series of momentary single, double and relatively long activations during the respective types of counts, thereby rendering more simplified and memorable the performance of such chronographic sequences using the single control element alone, one for each type of chronographic time count. These units and methods are provided in wristwatches which also exhibit digital displays of real time and include a further control element that is operable to switch the display in either direction between an ongoing chronographic time sequence and real time.
