shock

shock

[shok]
shock, any condition in which the circulatory system is unable to provide adequate circulation to the body tissues, also called circulatory failure or circulatory collapse. Shock results in the slowing of vital functions and in severe cases, if untreated, in death. It may be caused by inadequate pumping by the heart, by reduction of the blood volume due to dehydration or to loss of blood or plasma, or by reduced blood pressure resulting from dilation of the blood vessels. Inadequate pumping may occur as a result of various kinds of heart disease. Blood loss may result from injuries or from such internal conditions as bleeding ulcers. Burns produce extensive plasma loss from blood vessels into the burned area; crush injuries may result in loss of blood and plasma into the injured tissues. Dilation of blood vessels may be caused by injury to the nervous system, or by pain or emotional stress. Fainting is a form of shock brought about by a sudden reduction of the blood supply to the brain. Symptoms of shock include weakness, pallor, cold and moist skin, and thirst. The arterial blood pressure is reduced, the pulse is weak and rapid, and the surface veins of the limbs may collapse. Emergency aid for shock victims includes maintaining a clear breathing passage, administering oxygen, controlling bleeding, and keeping the patient warm and in a supine position with legs elevated. Therapy may include blood or plasma transfusion to restore the normal circulation, as well as treatment of the underlying cause of shock. The term shock is also applied to a variety of other conditions such as electric shock, allergic shock (see anaphylaxis), and emotional shock. See first aid.
G-Shock is a brand of watches manufactured by Casio, known for its resistance to shocks (e.g. hard knocks and strong vibrations). They were, and continue to be, designed primarily for sports and outdoor adventure oriented activity; for example, practically all G-Shocks have some kind of stopwatch feature, countdown timer, light and water resistance. Recent models have become more luxury and design oriented.

Today

The G-Shock was first produced in 1983. The line has expanded considerably since then and now includes atomic clock synchronization and Tough Solar functionality in the latest models. The Cockpit Series G-Shock is currently the official timekeeper of Nismo Racing. Many newer G-Shocks feature metal (steel or titanium) banding, and ornate analog timekeeping.

Twice a year (Spring/Summer and Fall/Winter collection) the basic models are updated. New limited models are introduced more frequently through the year. As with Swatch watches, G-Shocks have become collectors items. Arguably, the most sought after line is the Frogman. Limited edition Frogmans such as the Brazilian, Men in Yellow, Black Helios and Black Spots are some of the most desirable Frogmans.

Different series were developed for different target groups. The G-Lide (in Japan called X-Treme) series is specially for extreme sports like Skateboarding, Surfing and Snowboarding.

Casio also produces collaboration models, often with popular fashion brands, like A Bathing Ape (Bape), Stussy, Xlarge, KIKS TYO, Nano Universe, Levi's as well as Coca Cola and Marlboro.

Also there are special models released to put attention on the environment, like the International Cetacean Education and Research Centre (I.C.E.R.C.)models, also known as the Dolphin and Whales models.

G-Shock is very popular by rescue workers, police, astronauts, firemen and military. According to Mark Bowden's book Blackhawk Down, the DELTA Operators wore G-Shock watches during the combat events of Oct 3rd and 4th. Since then, G-Shocks watches have become very popular with Special Forces groups in both American and other NATO nation units, due to their being "battle tested".

Casio released "G-Shock Official Book" in 2006 in Japan, reviving the interest of (mostly Japanese) G-Shock collectors.

Models/Series

Baby-G

Baby-G was created as an addition to the G-Shock brand. The Baby-G brand is a sports digital watch aimed at young teens. Like the G-Shock, it is rugged. But unlike the G-Shock it is smaller, more compact, comes in designer colors, and has an added tele-memo feature that allowed the user to store 25 sets of data in the watch. Casio later retrofitted this feature to some of the larger styles of the G-Shock brand. Two thirds of Casio's Baby-G sales are in Casio's domestic market in Japan.
