History of Casio Gshock Watches

G-Shock DW-6600

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 with paramedics, police, astronauts, firefighters and soldiers. According to Mark Bowden's book Blackhawk Down, the DELTA Operators wore G-Shock watches during the combat events of October 3rd and October 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 the "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. Two thirds of Casio's Baby-G sales are in Casio's domestic market in Japan.[1][2]

Master of G
From Wikipedia, the free encyclopedia

The Master of G series were a collection of G-Shock watches produced by Japanese electronics and wristwatch manufacturer Casio in the late 1990s. There were several models in the range, of which many were designed to showcase a new form of technology that Casio had introduced into the G-Shock range, such as the Tough Solar power source and a digital compass.

History

The Master of G series began in 1985 with the G-Shock II, model number DW-5500C. This was a classic square G-Shock, but the bezel contained softer parts and slipped over the buttons. This way Casio created a Mud Resistant structure. The DW-5500C was therefore nicknamed "Mudman". It took until November before Casio came up with the Frogman model, however at this stage the watch was not called a Frogman. The Frogman was a heavy divers model that featured a unique asymmetrical design of thick rubber shielding around a self-contained module, with titanium screw-back case - an unusually high-cost design. A thick double-tang resin strap and multitude of digital features including dive timing completed a competent diver's watch. The Frogman proved to be very popular, and this is presumably one of the key reasons why at some point between then and 1995 Casio decided to produce more high-end premium models, and with them limited edition colour variants that, due to their scarcity, have in some cases become very valuable indeed.

It seems that the last of the "first wave" of Masters watches ceased production around 2000, but there are signs Casio is keen to keep the range alive, not just with limited edition releases but with re-designs of some of the old Masters, such as the new Mudman models released in 2006, followed by new Gulfman models in 2007.

Characteristics

Master of G series watches are invariably amongst the largest G-Shock designs Casio produces, usually suitable only for those with larger wrists. They almost always named with a "man" suffix, after the initial Frogman model which itself was named for scuba divers. Three models, the Mudman, Gaussman and Raysman all feature a thick rubber outer layer that surrounds the buttons and case completely, ensuring they offer mud-resistance. The Gaussman was also ISO-certified anti-magnetic.

Most models consist of a steel case surrounded by a thick neoprene or polyurethane bezel and outer protection. All models except the earliest Frogmen feature Casio's Illuminator display lighting system and are water resistant to 20 atmospheres (20bar/200metres), and are thus suitable for scuba-diving except at depths requiring helium-oxygen gas.

Some of the modules incorporate highly advanced functions. The Riseman featured twin sensors that measured both temperature and atmospheric pressure, thus allowing it to serve as a barometer and altimeter. The Raysman was the first model to make use of Tough Solar technology to power its functions, the Wademan featured a digital compass, the Fisherman helped introduce the now-common tide graph and moonphase readouts, and the Antman was the first watch Casio made that received an atomic signal that calibrated its timekeeping with atomic clock transponders in Japan.


It Started From Challenging The Common Sense
"Watches are thin and fragile --- that was the common sense. I wanted to challenge it". The man led the project team of G-SHOCK's development said, looking back the beginning. In 1981, the project team came up with the idea of "Triple Ten", that is, to build an ultimate watch which has 10 years life, water resistance up to 10 atmosphere, and endures the shock even when dropped to the ground from 10 meters height.
Design of project team "Tough" by Mr. Nikaido. These illustrations are the final sketch of No. 5000 model decided through intensive brain storming in the planning phase. They reveal how high quality the team has persuaded. To develop a watch endure the shock of free fall caused by gravity -- that was their concept. The name of the product "G-SHOCK" fully reflects the concept.

The title of "G" means --- The shock from fall can be the hardest shock for human being. The energy of shoot at hockey game could be, how strong it may be, dispersed by the bent of stick or the position of the person who receive it. However, the energy of fall won't be dispersed and can be ultimate damaging energy. "The resolution of the damaging energy" is the concept of "G". "G" has the ability. It doesn't mean that "G" is unbreakable regardless of the place and height it would be dropped, but "G" will work as long as the owner lives. That is the "G".

The G-SHOCK continues to kindle timepiece innovation, regardless of the era.
In 1983 the very first G-SHOCK was marketed under the product name "DW-5000C." Over 30 versions of the G-SHOCK have appeared on the market since; low-temperature proof models, mud-proof watches highly resistant to mud or dirt, versions with built-in temperature sensors, pressure sensors and other support features, a diver's watch and more. Indeed, the saga of the G-SHOCK can be said to comprise an ongoing series of revolutions which have truly shaken up the world of watches again and again.

Collectibility

Because they are no longer in production most of the Masters series command strong resale values; examples in NOS (New Old Stock) condition command a premium. Prices are sometimes higher outside of Japan, not least because many models were produced only for the domestic market rather than for North America and Europe.

There have been several limited editions of the Masters series, and depending on their scarcity these command some of the highest prices for any of Casio watches. The Men in Black and Men in Yellow series are black and yellow versions of the Masters and typically command anywhere between two and three times the resale value of the regular versions. Some models such as the "Brazilian" Frogman and A.R.T.P.I Wademan are even scarcer and can command even higher prices, though their value is hard to predict as there are limited numbers and the price is largely determined by demand from individual collectors.

Although not always available, all models are usually valued at 500 USD or less, providing an affordable alternative to the collecting of prestige watches.

Tough Solar
From Wikipedia, the free encyclopedia

Tough Solar is the name given by Casio to the solar powered battery charging system used in its G-Shock, ProTrek and Pathfinder line of watches. A self-contained, environmentally-friendly solar cell provides a supply of energy to the watch. Spare solar energy is saved in a battery. Normally, the solar cell and rechargeable battery should be able to last as long as the watch.

Casio Wave Ceptor
From Wikipedia, the free encyclopedia

The Casio Wave Ceptor is a line of radio watches by Casio. Wave Ceptor watches are able to calibrate themselves to the correct time by receiving time signals from various government time services around the world. These signals are normally driven directly by ultra-accurate atomic clocks, and so by synchronizing with the signals, the Wave Ceptor watches achieve unparalleled long-term accuracy - the same accuracy as the atomic clocks that drive the time signals, which is on the order of one second in three million years.

The Wave Ceptor watches are not the only radio-controlled wristwatches on the market. The German manufacturer Junghans and Japanese manufacturer Citizen Watch Co. also have this feature. Like most radio-controlled watches, the Wave Ceptor watches require no setting or resetting of time, date, daylight saving time, or year; and like most other watches of this kind, they synchronize at least every 24 hours, usually in the middle of the night. Their long-term and short-term accuracy is thus better than 500 ms.

A weakness shared by the Wave Ceptor watches with other radio-controlled watches is that they revert to merely free-running quartz accuracy in areas out of range or shielded from time setting signals. The time setting signals usually come from radio emitting towers. However, they are still as accurate as other quartz watches in this mode.

The receivers to which the watches can tune themselves vary by watch submodel. For example, in Europe, the watches will tune to DCF77 in Germany, or MSF in the United Kingdom. In the United States, they will tune to WWVB. In Japan, they will tune to JJY at 40kHz and 60kHz.

DW-5600C
From Wikipedia, the free encyclopedia

A Casio G-Shock DW-5600C in regular timekeeping mode.

The DW-5600C is one of Casio's early G-Shock model watches. Like its immediate predecessors, but unlike most newer models, it was cased in a heavy stainless steel screwback "tuna can." (Most current G-Shocks use a resin or composite case, and a stamped metal back held on by tiny screws.) Internal buffers around the module, a thick mineral-glass crystal, and a replaceable protective plastic bezel made the design resilient enough to withstand abuse which would destroy more traditional watch designs.

It was manufactured from 1987 through 1996. Many are still in use today, in part due to its rugged design. This model has also become something of a collectors' item among G-Shock aficionados.

It was flight-qualified by NASA for space missions'. [1]

The DW-5600C was superseded by:

* DW-5600E composite case and Illuminator, and electroluminescent backlight.
* G-5600 Tough Solar.
* GW-5600 Tough Solar and Wave Ceptor.
* GW-M5600 Tough Solar and Multi-band 5 Wave Ceptor.

Features

* Time display in 12-hour or 24-hour format. In regular timekeeping mode, the current home time is displayed to the second, along with the month, date, and day of the week, without any button presses.
* Auto-calendar correctly calculates month lengths, leap years and days-of-the-week between 1985 and 2029.
* Alarm: One alarm. An unusual feature is that in addition to the hour and minute, a month and/or date may optionally be set, so the alarm will only sound during the specified month or on the specified day of the month.
* Time signal (hourly chime.)
* Dual time: Hours and minutes can be set separately for a second time zone (seconds are synchronized with the home time.) The current home time is also displayed in dual time mode.
* Countdown timer: Can be set for any duration from one second up to 24 hours, in one-second increments; optional auto-repeat function. The current home time is also displayed in countdown timer mode.
* Stopwatch: 1/100th second, with one split; rolls over at 24 hours.
* Illumination: Backlight is via a tiny incandescent bulb at the left edge of the display.
* Reminder mark: A peculiar feature seldom seen on newer watches, this is a user-enabled display flag which slowly blinks in all modes. It has no function except to serve as a visual reminder to the wearer.
* Shock-resistant design, intended to survive a 10-meter fall.
* Water resistant to 200 meters.
* Battery: One lithium button cell, CR2320 in older models (module 691) or CR2016 in newer models (module 901.) Either was expected to last ten years or more.


Casio G-Shock Frogman
From Wikipedia, the free encyclopedia
Jump to: navigation, search

The Frogman is an high end model of the Casio G-Shock line. It was one of the first models of the "Master of G" line, a line of G-Shock's designed for special uses. The Frogman has an a-symmetrical shape and is also attached asymmetrical on its straps. It is specially made for scuba diving and is the only G-Shock with an ISO 200 water resistance rating.

The first Frogman (DW-6300) was released in November 1993. While Casio started to use the 4 screw back plate around that time, the DW-6300 had a classic screwback. In June 1995 a second generation Frogman came out. It was the DW-8200 model. From now on the Frogman became very popular under G-Shock collectors and many special editions were released.

A bit of a strange Frogman in the line up is the MRG-1100-2. This model was part of the MR-G series, a high end G-Shock line of metal models. While all other models have resin bezels, the MRG-1100 is all metal.

In April 1999 the DW-9900 model was introduced. This Frogman was slightly smaller than the DW-8200. For the next two years both DW-8200 and DW-9900 models were produced. The DW-9900 seems to be a less popular model as it was soon followed up with the GW-200 models in June 2001. Except for the "Snake Killer" and the "Carbon Fiber Frogman" (GW-201-6JF and GW-201NT-1JF), this Frogman has the Tough Solar 2242 module. Rumors have said several time that the GW-200 Frogman had its last release. The model has been around for at least 7 years, longer than the DW-8200. The letters "GW" in the model number suggests this model receives atomic clock signals, but that's not true. Possible the future 5th generation Frogman will have this feature.
