The G-Shock Black and Gold Master of G series consists of the GWN-1000GB-1A Gulfmaster, the GWG-1000GB-1A Mudmaster, and the GPW-1000GB-1A Gravitymaster. In recent times before this the Master of G special editions consisted of the all-digital Mudman, Rangeman, and Frogman models, and this is the first time a Master of G series consists of analog models. The recently released GWG-1000 Mudmaster was announced as a Master of G watch and this series confirms that the GWN-1000 Gulfmaster and GPW-1000 Gravitymaster are part of the Master of G professional line of G-Shock watches. Previously there were questions as to whether the international G-Shock websites outside of the USA considered the Gulfmaster and other analog models as Master of G watches and this appears to clear that up.
Casio America has announced the Gulfmaster GWN1000GB-1A (list price $550), Mudmaster GWG1000GB-1A (list price $800), and Gravitymaster GPW1000GB-1A (list price $1,000).
The black and gold color schemes are more conservative than we were expecting although the lighting is obviously an issue with some of these photos. (Update: The new Gulfmaster video below shows the gold parts are more dynamic than the photos suggest.) The Gulfmaster seems to be the most intriguing of the three, as far as standing out from other models in the same family. The GWN-1000GB-1A Gulfmaster seems to have a dark gold bezel that gives it somewhat of a vintage look, along with a gold crown and buttons. The GWG-1000GB-1A Mudmaster has a gold dial ring and a gold crown and buttons. The GPW-1000GB-1A Gravitymaster also has a gold dial ring, crown, buttons, and gold screws.
The Black and Gold Master of G series will be released in October in Japan with an international release to follow. Retail prices are 61,000 yen for the GWN-1000GB-1A Gulfmaster, 85,000 yen for the GWG-1000GB-1A Mudmaster, and 105,000 yen for the GPW-1000GB-1A Gravitymaster.
