Coin watch

A coin watch or medal watch comprises a watch inserted into a coin or medal. A coin watch is typically made by slicing a coin into two disks, one thinner than the other; or by removing one face of a coin. A watch is then embedded into the thicker part, and the two faces joined by a concealed hinge and catch. When closed, the watch is hidden and the coin looks like any other. Noted makers of coin watches include Cartier and Corum.

Rich black

Rich black, in printing, is an ink mixture of solid black over one or more of the other CMYK colors, resulting in a darker tone than black ink alone generates in a printing process. A typical rich black mixture might be 100% black, 50% of each of the other three inks. Other percentages are used to achieve specific results, for example 100% black with 70% cyan (C), 35% magenta (M), and 40% yellow (Y) is used to achieve "cool" black. "Warm Black" is 35%C, 60%M, 60%Y, and 100%K. The colored ink under the black ink makes a "richer" result; the additional inks absorb more light, resulting in a closer approximation of true black.

The term refers to either primarily black Western-style formal wear or to black traditional Japanese clothing worn at funerals and Buddhist memorial services. Other colors, particularly reds and bright shades, are considered inappropriate for mourning dress. If wearing Western clothes, women may wear a single strand of white pearls. Japanese-style mourning dress for women consists of a five-crested plain black silk kimono, black obi and black accessories worn over white undergarments, black sandals and white split-toe socks.

Luminous paint

radioluminescent paintfluorescent paintphosphorescent paint
Because of safety concerns and tighter regulation, consumer products such as clocks and watches now increasingly use phosphorescent rather than radioluminescent substances. Radioluminescent paint may still be preferred in specialist applications, such as diving watches. Radioluminescent paint was invented in 1908 by Sabin Arnold von Sochocky and originally incorporated radium-226. Radium paint was widely used for 40 years on the faces of watches, compasses, and aircraft instruments, so they could be read in the dark. Radium is a radiological hazard, emitting gamma rays that can penetrate a glass watch dial and into human tissue.


Team Tissot
Tissot introduced the first mass-produced pocket watch as well as the first pocket watch with two time zones in 1853 and the first anti-magnetic watch, in 1929–30. Charles-Emile Tissot left for Russia in 1858 and succeeded in selling their savonnette pocket watches across the Russian Empire. The Tissot company was also the first to make watches out of plastic (Idea 2001 in 1971), stone (the Alpine granite RockWatch in 1985), mother of pearl (the Pearl watch in 1987), and wood (the Wood watch in 1988). Tissot merged with Omega in 1930 and Tissot-Omega watches from this era are sought after by collectors.

The technology was purchased by Google and the service ended on March 31, 2015. 2014 Apple introduced Apple Pay for NFC-enabled mobile payment on iPhone 6 and 6 Plus, and the Apple Watch, which was released on April 24, 2015. In November 2015, Swatch and Visa Inc. announced a partnership to enable NFC financial transactions using the "Swatch Bellamy" wristwatch. The system is currently online in Asia thanks to a partnership with China UnionPay and Bank of Communications. The partnership will bring the technology to the US, Brazil, and Switzerland. November 2015, Google’s Android Pay function was launched, a direct rival to Apple Pay, and it started rolling out across the US.

Petrodvorets Watch Factory

In its glory years after the war, the plant employed 8,000 people, produced 4.5 million watches per year for Soviet citizens and the needs of the Red Army. The plant was equipped with two atomic bunkers that could accommodate 8,000 people in case of a western nuclear attack, had its own schools, university, hospital, resorts on the Black Sea, camps for Communist Youth Pioneer organization and Komsomol and its orchestras. Today, the plant has dramatically cut production following the troubled years of privatization and the collapse of the Soviet Union.

However, there are quartz movements, even in wrist watches such as the Omega Marine Chronometer, that are accurate to within 5 or 20 seconds per year. At least one quartz chronometer made for advanced navigation utilizes multiple quartz crystals which are corrected by a computer using an average value, in addition to GPS time signal corrections.

Visible spectrum

visiblevisible lightspectrum
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to 740 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz.
