Seiko
, commonly known as Seiko ( , ), is a Japanese maker of watches, clocks, electronic devices, and semiconductors. Founded in 1881 by Kintarō Hattori in Tokyo, Seiko introduced the world's first commercial quartz wristwatch in 1969. Seiko is widely known for its wristwatches. Seiko and Rolex are the only two watch companies considered to be vertically integrated. Seiko is able to design and develop all the components of a watch, as well as assemble, adjust, inspect and ship them in-house. Seiko's mechanical watches consist of approximately 200 parts, and the company has the technology and production facilities to design and manufacture all of these parts in-house. The company was incorporated (K. Hattori & Co., Ltd.) in 1917 and renamed Hattori Seiko Co., Ltd. in 1983 and Seiko Corporation in 1990. After reconstructing and creating its operating subsidiaries (such as Seiko Watch Corporation and Seiko Clock Inc.), it became a holding company in 2001 and was renamed Seiko Hol ...

Watch
A watch is a timepiece carried or worn by a person. It is designed to maintain a consistent movement despite the motions caused by the person's activities. A wristwatch is worn around the wrist, attached by a watch strap or another type of bracelet, including metal bands or leather straps. A pocket watch is carried in a pocket, often attached to a chain. A stopwatch is a type of watch that measures intervals of time. During most of their history, beginning in the 16th century, watches were mechanical devices, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are known as '' mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, powered by a battery and keeping time with a vibrating quartz crystal. By the 1980s it had taken over most of the watch market, in what became known as the quartz revolution (or the quartz crisis in Switzerland, whose renowned watch industry it decima ...

Wako (retailer)
is a department store retailer in Japan, best known for its flagship store, commonly referred to as the Ginza Wako, located in the heart of Tokyo’s Ginza shopping district. The store is renowned for its watches, jewelry, chocolate, porcelain, dishware, handbags, and upscale imported goods. Wako Co., Ltd. was established in 1947 as the successor to the retail division of K. Hattori (known in Japan as Hattori Tokeiten, now Seiko) and began operations in a temporary location. In 1952, it commenced business in its current building. The Ginza Wako building was originally completed in 1932 as the headquarters of K. Hattori, situated at the corner of the Ginza 4-chome intersection. The Seiko headquarters was later relocated to Toranomon, and in 2016, it moved to Ginza 1-chome. In 2022, the Ginza Wako building was reopened as Seiko House Ginza following renovation work. In addition to its main store, Ginza Wako, Wako operates five branches in the Ginza area, including Seiko Dream Squ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz Clock
Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. The crystal oscillator, controlled by the resonant mechanical vibrations of the quartz crystal, 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 numerical time display, usually in units of hours, minutes, and seconds. As the advent of solid-state digital electronics in the 1980s allowed them to be made more compact and inexpensive, quartz timekeepers became the world's most widely used timekeeping technology, used in most clocks and watches as well as computers and other appliances that keep time. Explanation Chemically, quartz is a specific form of a compound called silicon dioxide. Many materials can be formed into plates that will resonate. However, quart ...

Kintarō Hattori
Kintarō Hattori (服部 金太郎, November 21, 1860 – March 1, 1934) was a Japanese businessman and one of the first and most important Japanese watchmakers in history, as well as the founder of Seiko, one of the world's largest manufacturers of watches. He was a permanent council member of the Japanese Red Cross. Early life Kintarō Hattori was born in Uneme-cho, Kyōbashi, Tokyo, on November 21, 1860, to a well-established family of merchants.

Clock
A clock or chronometer is a device that measures and displays time. The clock is one of the oldest Invention, human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month, and the year. Devices operating on several physical processes have been used over the Millennium, millennia. Some predecessors to the modern clock may be considered "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels., pp. 103–104., p. 31. Traditionally, in horology (the study of timekeeping), the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ginza
Ginza ( ; ) is a district of Chūō, Tokyo, Chūō, Tokyo, located south of Yaesu and Kyōbashi, Tokyo, Kyōbashi, west of Tsukiji, east of Yūrakuchō and Uchisaiwaichō, and north of Shinbashi.

Mechanical Watch
A mechanical watch is a watch that uses a Movement (clockwork), clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio clock, radio watches, which are quartz watches synchronized to an atomic clock via radio waves. A mechanical watch is driven by a mainspring which must be wound either periodically by hand or via a Automatic watch, self-winding mechanism. Its force is transmitted through a series of gears to power the balance wheel, a weighted wheel which oscillates back and forth at a constant rate. A device called an escapement releases the watch's wheels to move forward a small amount with each swing of the balance wheel, moving the watch's hands forward at a constant rate. The escapement is what makes the 'ticking' sound which is heard in an operating mechanical watch. Mechanical watches evolved in Europe in the 17th century from spring powered clocks, which appe ...
