Starting from the end of the 1990s, G-SHOCK has been issuing special models in collaboration with and in support of various different environmental organizations. Based on the G-SHOCK theme of "Love The Sea And The Earth", these collaboration models support the activities of WILDLIFE PROMISING, an Authorized Nonprofit Corporation (NPO) that works towards coexistence between wildlife and humans in Africa. The designs are inspired by the skin pattern of the African rock python, which is the largest snake in Africa and a species registered as endangered wildlife under the Washington Convention. Base model is the MTGB1000, which is decorated with the African rock python pattern. The back of this model sports a "Love The Sea And The Earth" logo mark. Special packaging is also decorated with the African rock python motif. Connected Engine supports time correction using a calibration signal and Bluetooth® connection. A Bluetooth® communication function makes it possible to connect with a smartphone running the G-SHOCK Connected app and obtain accurate time information from an on-line time server. MULTIBAND 6 automatically adjusts time settings based on reception of one of six calibration signals around the globe when you are within the range of a signal, even if connection with a smartphone is not possible for some reason. All of this means that timekeeping is accurate, no matter where in the world you happen to be. G-SHOCK is dedicated to the continued creation of models in collaboration with various environmental groups under the theme of "Love The Sea And The Earth".
