The AE-1000W has a 1/100 stopwatch which can count up to 24 hours (23:59'59.99") and has an elapsed time, split time and final time recording. The watch has an hourly chime mode and five daily alarms (also written on the face of the watch) for recurring events along with a one-time alarm which can be switched off using any button.
The watch had a small lens at the top of its face used for data transmission by visible light. [5] [21] Data was transmitted from the CRT of the computer through a series of pulsating horizontal bars, [22] [23] that were focused by the lens and written to the watch EEPROM memory through an optoelectronic transducer operating in the visible light spectrum and employing optical scanning technology.
A typical kitchen timer. A timer or countdown timer is a type of clock that starts from a specified time duration and stops upon reaching 00:00. An example of a simple timer is an hourglass. Commonly, a timer triggers an alarm when it ends. A timer can be implemented through hardware or software.
The first digital watch was the Pulsar, introduced by the Hamilton Watch Company in 1972. The "Pulsar" became a brand name, and would later be acquired by Seiko in 1978. In 1982, a Pulsar watch (NL C01) was released which could store 24 digits, likely making it the first watch with user-programmable memory, or the first "memorybank" watch.

List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
For example, the Tektronix 7D11 Digital Delay uses a counter architecture. [25] A digital delay may be set from 100 ns to 1 s in 100 ns increments. An analog circuit provides an additional fine delay of 0 to 100 ns. A 5 MHz reference clock drives a phase-locked loop to produce a stable 500 MHz clock. It is this fast clock that is gated by the ...
The watches were priced at $34.95, and all were sold at the event. [1] After a $20 million advertising campaign featuring toughness tests performed on the watch, the Triathlon became a success. In 1986, Timex acquired the rights to the Ironman name, and developed the Ironman Triathlon watch based on the 1984 Timex Triathlon watch.
