Pulsar is a brand of watch and currently a division of Seiko Watch Corporation of America (SCA). Pulsar was the world's first electronic digital watch. Today Pulsar watches are mostly analog and use the same movements in Seikos such as the 7T62 quartz chronograph movement.
In 1970, Pulsar was a brand of the American Hamilton Watch Company which first announced that it was making and bringing the LED watch to market. It was developed jointly by American companies Hamilton and Electro/Data Inc.
In spring 1972, –created with light-emitting diodes (LEDs). A button was pressed to display the time. The first Pulsar initially sold for $2100 ($13,300 in 2019 dollars).the first Pulsar watch was marketed by Hamilton Watch (the parent company, not the Hamilton Watch Division). With an 18-carat gold case, the world's first all-electronic digital watch was also the first to use a digital display
In October 1972, the Potpourri segment in the issue of Playboy mentioned the first Pulsar –and carried a photo.
In 1975, a digital Pulsar with a built-in calculator (operated with small buttons) was released.
In 1978, Seiko Corporation acquired the Pulsar brand, it serves as Seiko's mid-grade offerings.
In March 2020, Seiko stopped distribution of Pulsar in the United Kingdom.[ citation needed ]
A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device.
A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain. The study of timekeeping is known as horology.
A flat-panel display (FPD) is an electronic display device used to enable people to see content in a range of entertainment, consumer electronics, personal computer, and mobile devices, and many types of medical, transportation and industrial equipment. They are far lighter and thinner than traditional cathode ray tube (CRT) television sets and are usually less than 10 centimetres (3.9 in) thick. Flat-panel displays can be divided into two display device categories: volatile and static. Volatile displays require that pixels be periodically electronically refreshed to retain their state. A volatile display only shows an image when it has battery or AC mains power. Static flat-panel displays rely on materials whose color states are bistable, and as such, flat-panel displays retain the text or images on the screen even when the power is off. As of 2016, flat-panel displays have almost completely replaced old CRT displays. In many 2010-era applications, specifically small portable devices such as laptops, mobile phones, smartphones, digital cameras, camcorders, point-and-shoot cameras, and pocket video cameras, any display disadvantages of flat-panels are made up for by portability advantages.
A display device is an output device for presentation of information in visual or tactile form. When the input information that is supplied has an electrical signal the display is called an electronic display.

The Hamilton Watch Company is a Swiss manufacturer of wristwatches based in Bienne, Switzerland. Founded in 1892 as an American company, Hamilton Watch Company ended American manufacture in 1969. Through a series of mergers and acquisitions, the Hamilton Watch Company eventually became integrated into the Swatch Group, the world's largest watch manufacturing and marketing conglomerate.
Citizen Watch Co., Ltd. is an electronics company primarily known for its watches, and is the core company of a Japanese global corporate group based in Tokyo, Japan. In addition to Citizen brand watches, it is the parent of American watch company Bulova, and is also known for manufacturing small electronics such as calculators.
A digital clock is a type of clock that displays the time digitally, as opposed to an analogue clock. the time is indicated digitally.
A calculator watch is a digital watch with a built-in calculator, usually including buttons on the watch face. Calculator watches were first introduced in the 1970s and continue to be produced, despite falling from their peak popularity during the 1980s. The most dominant brands in the end was the Casio Databank series and Timex.
Automatic quartz is a collective term describing watch movements that combine a self-winding rotor mechanism to generate electricity with a piezoelectric quartz crystal as its timing element. Such movements aim to provide the advantages of quartz without the inconvenience and environmental impact of batteries. Several manufacturers employ this technique.
Nichia Corporation is a Japanese chemical engineering and manufacturing company headquartered in Anan, Japan with global subsidiaries. It specializes in the manufacturing and distribution of phosphors, including light-emitting diodes (LEDs), laser diodes, battery materials, and calcium chloride.
In watchmaking, the quartz crisis is the upheaval in the industry caused by the advent of quartz watches in the 1970s and early 1980s, that largely replaced mechanical watches around the world. It caused a significant decline of the Swiss watchmaking industry, which chose to remain focused on traditional mechanical watches, while the majority of the world's watch production shifted to Asian companies such as Seiko, Citizen and Casio in Japan that embraced the new electronic technology.
A LED display is a flat panel display that uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors where they are visible in the sun for store signs and billboards. In recent years, they have also become commonly used in destination signs on public transport vehicles, as well as variable-message signs on highways. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative purposes. LED displays can offer higher contrast ratios than a projector and are thus an alternative to traditional projection screens, and they can be used for large, uninterrupted video walls. microLED displays are LED displays with smaller LEDs, which poses significant development challenges.

Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks and watches are at least an order of magnitude more accurate than mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds.
Unisonic Products Corporation was an American manufacturer and distributor of consumer electronics from the 1970s to the 1990s. Although headquartered in New York City, Unisonic outsourced its manufacturing operations to various facilities in East Asia. Unisonic developed a variety of electronics, including calculators, CRT television sets, video game consoles, digital watches, telephones, answering machines, and digital alarm clocks.
A smartwatch is a wearable computer in the form of a watch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides for management and telemetry. While early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing, 2010s smartwatches have more general functionality closer to smartphones, including mobile apps, a mobile operating system and WiFi/Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth headset. Some models, called watch phones, have mobile cellular functionality like making calls.
