CARBON CORE GUARD STRUCTURE
A new shock-resistant carbon core guard structure integrates the case. An external structure capitalises on its toughness and lightness. This also enables removing the button guards from the exterior.
DUAL-LAYERED CASE BACK
GA-2000 features a stainless-steel panel back that keeps the watch airtight, as well as a fine resin glass fibre case back that makes it tough against shocks.
