, commonly known as Seiko ( , ), is a Japan, Japanese maker of watches, clocks, electronic devices, semiconductors, jewelry, and optics, optical products. Founded in 1881 by Kintarō Hattori in Tokyo, Seiko introduced the world's first commercial Quartz clock, quartz wristwatch in 1969. Seiko is widely known for its wristwatches. Seiko, Citizen Watch, Citizen and Rolex are the only three watch companies considered to be Vertical integration, 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 Wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wako (retailer)
is a department store retailer in Japan, whose best known store (commonly known as the Ginza Wako) is at the heart of the Ginza shopping district in Tokyo. This store is famous for its watches, jewellery, chocolate, porcelain, dishware, and handbags, as well as upscale foreign goods. There is an art gallery, called Wako Hall, on the sixth floor. Wako was founded in 1881 by Kintarō Hattori as a watch and jewelry shop called K. Hattori (now Seiko Group Corporation) in Ginza. In 1947, the retail division split off as Wako Co., Ltd. From 1894 to 1921, the Hattori Clock Tower stood on the site that Wako occupies today. In 1921, the Hattori Clock Tower was demolished to rebuild a new one. The reconstruction was delayed due to the Great Kantō earthquake of September 1, 1923. The new tower was completed in 1932 as the K. Hattori Building. In homage to its predecessor, the new store was also fitted with a clock. The 1932 building was designed by Jin Watanabe in art deco influenced ne ...

Musical Instrument
A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The date and origin of the first device considered a musical instrument is disputed. The oldest object that some scholars refer to as a musical instrument, a simple flute, dates back as far as 50,000 - 60,000 years. Some consensus dates early flutes to about 40,000 years ago. However, most historians ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holding Company
A holding company is a company whose primary business is holding a controlling interest in the securities of other companies. A holding company usually does not produce goods or services itself. Its purpose is to own shares of other companies to form a corporate group. In some jurisdictions around the world, holding companies are called parent companies, which, besides holding stock in other companies, can conduct trade and other business activities themselves. Holding companies reduce risk for the shareholders, and can permit the ownership and control of a number of different companies. '' The New York Times'' also refers to the term as ''parent holding company.'' Holding companies are also created to hold assets such as intellectual property or trade secrets, that are protected from the operating company. That creates a smaller risk when it comes to litigation. In the United States, 80% of stock, in voting and value, must be owned before tax consolidation benefits such ...

Mechanical Watch
A mechanical watch is a watch that uses a 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 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 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 appeared in the 15th century. Mechanical watches are ...

Vertical Integration
In microeconomics, management and international political economy, vertical integration is a term that describes the arrangement in which the supply chain of a company is integrated and owned by that company. Usually each member of the supply chain produces a different product or (market-specific) service, and the products combine to satisfy a common need. It contrasts with horizontal integration, wherein a company produces several items that are related to one another. Vertical integration has also described management styles that bring large portions of the supply chain not only under a common ownership but also into one corporation (as in the 1920s when the Ford River Rouge Complex began making much of its own steel rather than buying it from suppliers). Vertical integration and expansion is desired because it secures supplies needed by the firm to produce its product and the market needed to sell the product. Vertical integration and expansion can become undesirable wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watch
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. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are called '' mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolex
Rolex SA () is a British-founded Swiss watch designer and manufacturer based in Geneva, Switzerland. Founded in 1905 as ''Wilsdorf and Davis'' by Hans Wilsdorf and Alfred Davis in London, the company registered ''Rolex'' as the brand name of its watches in 1908 and became ''Rolex Watch Co. Ltd.'' in 1915. After World War I, the company moved its base of operations to Geneva because of the unfavorable economy in the United Kingdom. In 1920, Hans Wilsdorf registered ''Montres Rolex SA'' in Geneva as the new company name (''montre'' is French for wristwatch); it later became ''Rolex SA''. Since 1960, the company has been owned by the Hans Wilsdorf Foundation, a private family trust. Rolex SA and its subsidiary Montres Tudor SA design, make, distribute, and service wristwatches sold under the Rolex and Tudor brands. History Early history Alfred Davis and his brother-in-law Hans Wilsdorf founded ''Wilsdorf and Davis'', the company that would eventually become ''Rolex SA'', ...

Citizen Watch
is an electronics company primarily known for its watches and is the core company of a Japanese global corporate group based in Nishitokyo, 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. History The company was founded in 1930 by Japanese and Swiss investors. It took over Shokosha Watch Research Institute (founded in 1918) and some facilities of the assembly plant opened in Yokohama in 1912 by the Swiss watchmaker Rodolphe Schmid. The brand Citizen was first registered in Switzerland by Schmid in 1918 for watches he sold in Japan. The development of this brand was supported in the 1920s by Count Gotō Shinpei with his hope that watches could become affordable to the general public. The growth of Citizen until World War II relied on technology transfer from Switzerland. Products Atomic timekeeping Citizen launched the world's first multi-ba ...

Quartz Clock
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 numerical time display, usually in units of hours, minutes, and seconds. Since the 1980s, when the advent of solid-state digital electronics allowed them to be made compact and inexpensive, quartz timekeepers have become 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, quartz is also a piezoelectric material: that is, when a quartz crystal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that can ...
