New shock resistant construction Carbon Core Guard A new shock resistant Carbon Core Guard integrates the case and back cover into a monocoque case that protects the module. An external structure that capitalizes on the high strength and lightweight characteristics of the material used dramatically improves toughness while also enabling a weight of only 72 grams, making this the lightest model in the GRAVITYMASTER Series.
Lightweight, resists rust. Rust-resistant structure Buttons, button pipes, case internal fixing rings, and other metal parts exposed to outside air are made of strong, lightweight, and highly rust resistant titanium alloy.
Stands up to rough use Carbon fiber insert band Carbon fiber of outstanding tensile strength is molded into urethane resin for a band that resists breaking.
