CASIO G-SHOCK GA-2100-1A Men's Analog-Digital Watch Black Neobrite Carbon Core Guard 200m Water Resistant

■ Product Overview

The CASIO G-SHOCK GA-2100-1A is a black analog-digital watch from the iconic 2100 Series.

Its octagonal design inherits elements from the original DW-5000C while combining a slim profile with G-SHOCK toughness. Contrasting hands and hour markers provide a different appearance from the all-black GA-2100-1A1 variation.

Neobrite and the white LED Super Illuminator are separate visibility features.

The 200-meter water-resistance rating does not mean that the watch is certified as a professional diving instrument. Follow the included instructions and do not operate the buttons underwater unless expressly permitted.
