This all-new model has a Carbon Core Guard structure that consists of a Dual Core Guard monocoque (single shell) case that is surrounded by a stainless steel metal frame. This gives the watch a seamlessly integrated case back and a more refined metallic look from the front and sides, unlike previous MT-G models that also had large resin parts on the sides. Other major features include Tough Solar power, Multi-Band 6 automatic radio time-syncing, Bluetooth smartphone link, Triple G Resist protection (against shock, centrifugal force, and heavy vibration), and 200-meter water resistance.
