Eesti: Veekell Yazdi veemuuseumis Iraanis. Poolkerajas kausike asetatakse veepinnale ja vesi hakkab sellesse sisse voolama põhjas asuva augukese kaudu. „Aeg on täis“, kui kausike on tervenisti veega täitunud. Selliste veekelladega mõõdeti (ja mõõdetavat veel praegugi) Iraanis küla ühisest veejuhtimissüsteemist iga üksiku talupidaja põldude niisutamiseks ette nähtud aega.
English: Water clock in Yazd Water Museum (Iran). Water flows slowly to the (upper) small bowl through its bottom hole. In Iran, such clocks have been (and are still) used to measure the watering time of each separate farm from shared irrigation system of the village.
