The G-Shock GM-2100 is one of the most highly anticipated releases of the year, featuring a stainless steel octagonal bezel based on the bestselling GA-2100. The Casio A100 is a retro-revival model that is a metal version of the classic 1978 Casio F-100 seen in the movie “Alien.” YouTube channel Debajo del Reloj is one of the first to publish hands-on (or on-wrist) videos of the GM-2100 and Casio A100 launch models.
The GM-2100 is coming in August 2021 to Japan and Asia, and will also be released worldwide (with a U.S. list price of $200-$220). The Casio A100 is scheduled for an August release for around $90, but the exact details are not yet known.
