The world-popular Big Case Series continues to grow with the addition of new models created by combining and layering parts in a way that creates a multi-dimensional look. A big rotary switch at 3 oclock adds to the overall design and also enables intuitive operation of various functions. A choice of colors includes basic black and white, as well as tri-color combinations for the case, band, hour markers and dial. An LED illumination system allows easy viewing even in the dark.
