MASTER OF G is a professional series built for those who challenge the limits. By adopting a utilitarian tan colour and eliminating unnecessary decorative elements, the colour scheme strongly expresses the identity of a series dedicated to true practicality and functionality. The FROGMAN GWF-D1000BC features an all-black base accented effectively with tan-coloured details. The bezel is treated with a DLC coating, while the front screws receive a black IP finish, enhancing the premium metallic texture. It also features a composite metal-and-resin band, combining exceptional strength with lightweight comfort. The band is equipped with a two-stage adjustable extension mechanism, allowing the watch to be worn easily even over a wetsuit. Its construction, functions and design are all born from a focus on practicality. With a colour scheme perfectly suited to such uncompromising toughness gear, this model expresses the true essence of MASTER OF G more strongly than ever.
