Introducing the GA-500 Series from G-SHOCK. Round faces combined with multi-dimensional hands and new resin molding technology create a bike-like dial-and-wheel motif for a totally new and unique sports design. These are the first digital-analog combination models equipped with large front buttons at 6 o’clock for one press stopwatch operation. Great design, a collection of useful functions, and more all add up to make the new G-SHOCK GA-500 the perfect choice for a wide range of timekeeping needs.
