This new model come with metal parts and buttons, and offer a choice rose gold accent coloring on the iconic disk dial at 9 o'clock. The colors of this watch give it a look that is both sporty and elegant. The bezel of the GST-B100XB models has a highly fashionable design, and is made of lightweight yet very rigid carbon material. Combining state-of-the-art Toray Industries TORAYCA®*1 and NANOALLOY®*2 results in a bezel with outstanding shock resistance characteristics. Highly scratch resistant clear sapphire glass is used for the crystal to enhance readability and appearance, and to create a design that is both tough and good looking. The hefty urethane band features a sporty outer surface pattern that improves its fit and looks great as well. A metal band ring reduces the chance of band breakage due to abrasion.
