CASIO MT-G the premium line watches are inspired by the adventurous men who grew up with G-SHOCK watches, and now rediscovered their charm, but require from their timepiece much more professional appearance. Therefore, CASIO launched watches line that combines top steel with composite resin to achieve the highest possible level of resistance watches. All watches of MTG series go under intensive triple G testing. The first test is a crash test when the watches are repeatedly thrown by force onto a hard surface and examined for their accuracy and protection of key components. The second test is the overload test. Watches are placed in a centrifuge and subjected to an overload of a force of 15 G. Watches pass the test successfully only if all functions are working properly and stopwatch still measures time with an accuracy of 1/100 of a second even in such conditions of gravitational acceleration. That corresponds to ISO 2669, which is used to test aircraft instruments. The third test is the test of strong vibrations. Watches are placed on a vibrating platform, which has an amplitude 20 mm and vibrational acceleration of 20 G for ten hours. Testing takes place in accordance with JIS D1601, which is used for vibration testing of automotive components. All MTG line watches are powered by solar energy through integrated solar panel. Therefore the standard watches battery replacement is eliminated. For watches power serves all kinds of light. It does not matter if watches are outside or inside, they always recharge. The watches accuracy is controlled by hybrid technology, respectively , the two technologies are paired in order to appropriately complement each other. The first technology is radio signal reception. The watches are equipped with a receiver capable of receiving signals from six stations located around the world (Germany, Great Britain, North America, China and the two stations in Japan). This technology is complemented by another one, which can receive time signals from global positioning satellites and GPS navigation system. Watches then recognize, in which time zone they are located and automatically adjust the current time. As well as everything else in this line of watches, their innovative design utilizes the advantages of steel and composite resin. Watches case is a sandwich construction, the upper part and the crown are made of high-grade steel between these components is resin part that is flexible and can protect the internal mechanism of watches. The entire corpus is firmly connected with four tube connection that provides even greater toughness. The dial is covered with sapphire crystal, which is equipped with an anti-reflective coating. The lug is again made from stainless steel and the inner parts are provided with resinous parts for more comfortable wear. Watches are controlled by the quartz movement, which is equipped with five electromotors for quick and accurate setting.The electromotor for the main hands is even doubled for a maximum rapid traverse. Watches naturally abound with standard G-SHOCK watches features such as dial LED lighting Super illuminator,(watches also contain the luminescent layer on hands), stopwatches with accuracy 1/100 of a second, indicator for the second time zone or waterproofness to 200 meters in depth. An interesting point is that MT-G watches are equipped with hands made of carbon fiber. Watches are controlled using the Smart Access crown, that facilitates and accelerates handling.
