Calculators, alarms, laptimers, and stopwatch features began to appear on electronic watches as manufacturers learned to load up the watch module's integrated circuits with features.
Pulsar introduced the world's first calculator watch in 1975. The Pulsar calculator watch counts hours, minutes, and seconds, as well as keeping track of the month and date. As a calculator it adds, subtracts, multiplies, and divides. It has a percent key, floating decimal and a memory function. A small plastic tool was provided to push the recessed keys.
A small number of these watches were sold in gold cases for $3950. They were sold in less expensive cases for $600. Other companies, such as Hewlett Packard and Citizen, soon followed with their own versions of the calculator watch. Today watches with many features can be purchased very cheaply.
