FEATURES

Shock-, dust-, and mud-resistant structure delivered by carbon fiber-reinforced resin

Offering strength, lightness and excellent weather resistance, a carbon fibre-reinforced resin case protects the module. Gaskets are applied around the buttons to ensure a tight seal, providing reliable dust and mud resistance even in harsh environments. Carbon fiber-reinforced resin is also used for the cover enclosing the case back and for the movable parts on the underside of the band, enhancing both durability and wearing comfort.
