G-Shock was introduced in 1983 as a result of the quest for the ultimate in shock-resistant watches. Since then it has become an icon of technical ingenuity and robustness. Over the years, there has been a great range of colors, designs and features, but the most special and exclusive models are always reserved for the exclusive G-Shock Premium collection. Within the Premium collection, MR-G and MT-G stand out for their stylish designs, high quality materials and cutting-edge technology. The use of titanium and/or steel combined with the extremely high quality finish, provide a stylish look without losing the distinctive functionality and ergonomics of the G-Shock brand. The Masters of G collection includes Mudmaster, the Gravity Master and the Gulf Master. Each of the models has its own strengths and intended audience - on land, at sea or in the air - to which its functionality is matched.
