This model is made shock-resistant by its materials. Jointly developed with Mizuno Technics Co., Ltd., this model features a strong band made hard to cut by inserting carbon fiber with excellent tensile durability into resin. With attention to even the smallest details, carbon fiber is inserted around the spring bar of the case connecting lug, around the buckle, and into the free loop, etc. Titanium is used for the metal parts like the back cover, side buttons, and buckle, etc. The back cover is forged to make it shock-resistant and durable. The design leverages the texture of the carbon fiber to create a stylish finish.
