ABSTRACT:
An arrangement for indicating elapsed time is disclosed that is particularly useful in marine timepieces, divers' wristwatches and the like. The arrangement utilizes a light-emitting member which, upon the lapsing of a predetermined time is energized to give visual indication to the wearer of the elapsed time. A mechanical switching structure is described that is controlled by the movement of the timepiece and which upon closure causes the light emitting member to be energized. An electronic circuit is provided which causes the light emitting member to flash when energized.
