Details

Octagonal form exudes toughness

The bezel adopts the octagonal design motif
the G-SHOCK has featured since the very first
watch. Undergoing painstaking processes of
forging, cutting and polishing, the bezel is
precisely crafted — from its intricately
shaped face to the form of its back, which is
the key to the precision fit it makes with the
inner case. A round hairline finish is applied
to the top surface and a mirror polish to the
sides, giving the bezel a beautiful gleam.

Ever evolving toughness: Metal-clad shock-resistant structure

A stainless steel bezel with exceptional strength and inner case made of damage- and deformation-resistant glass fibre-reinforced resin safeguards the module. Tiny protrusions on the inner case reduce surface contact with the bezel to cushion shocks to the module. Cutting-edge technology is applied to the original G-SHOCK concept of hollow construction to deliver a shock-resistant structure with a metal exterior.
