G-Shock

The line of G-shock watches now includes atomic clock synchronization and Tough Solar[clarification needed] functionality. The Cockpit Series G-Shock is the official timekeeper of Nismo Racing. Many newer G-Shocks feature metal (steel or titanium) banding and analog timekeeping.Twice a year 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.Casio also produces collaboration models, often with popular fashion brands, like A Bathing Ape (Bape), Stussy, Xlarge, KIKS TYO, Nano Universe, Levi's, Lifted Research Group, as well as Coca Cola, Pulp68 Skateshop, Lucky Strike and Marlboro.G-Shock watches are popular with mountaineers, firemen, paramedics, people working in the offshore, police officers, astronauts, film directors (Tony Scott was often pictured wearing a GW-3000B, as is Ron Howard and Francis Ford Coppola) and soldiers. Ex-Special Forces-British SAS soldier Andy McNab mentions in several of his novels how his fictional character Nick Stone relies on a G-Shock watch. According to Mark Bowden's book Blackhawk Down, the DELTA Operators wore G-Shock watches during the combat events of 3 & 4 October 1993. Since then, G-Shock watches have become very popular with Special Forces groups in both American and other NATO nation units, due to their being "battle tested".Models DW-5600C, DW-5600E, DW-5900, DW-6600, DW-6900 are flight-qualified for NASA space travel. Casio has updated the DW-5600E module, replacing the usual 1545 module with module number 3229 (in 2010).In 2012, Casio released GB-6900, a Bluetooth-capable model of G-Shock. Casio claimed the battery life of 2 years on a single CR2032 battery.[9]Casio continues to add new features to G-Shock watches. Some include Tough Solar battery charging and Multiband 6 time synchronization through radio signals from six transmission stations worldwide. The GW-9400 Rangeman and GWN-1000 Gulfmaster models have a Triple Sensor with a digital compass, thermometer, and barometer/altimeter. The MTG-S1000, GW-A1000, and GPW-1000 feature Triple G Resist which includes resistance to shock, centrifugal gravity, and vibration. In 2014 Casio introduced the GPS Hybrid Wave Ceptor feature in the GPW-1000 Gravitymaster that allows the watch to synchronize the time through GPS signals and also adjusts the time zone automatically. The MRG-G1000 is also equipped with this feature.
