Casio G-SHOCK GM-B2100GD-9A

Dressed in a yellow-gold toned stainless steel case and paired with a matching metal bracelet, the Casio G-SHOCK GM-B2100GD-9A is a latest iteration of the full metal CASIOAK watch.

In the “2100” series, the digital/analog combination model “GA-2100”, which arranged the first “G-SHOCK” machine in a modern style, was released in 2019.

The characteristic octagonal bezel and thin and simple design have been well received all over the world. Following its footsteps, the brand also released a Bluetooth enabled variant named GA-B2100. In addition, in August of last year, the GM-B2100, which adopted stainless steel for exterior parts such as the bezel, band, and screw-back case, has evolved.

The new GM-B2100GD-9A model uses yellow gold as a color variation of the Full Metal G-SHOCK GM-B2100. In addition to the bezel and band, yellow gold IP has been applied to small parts such as side buttons and screws. The beautiful texture of the metal is enhanced by using hairline processing on the top surface of the bezel and the band, and mirror processing on the slope of the bezel.

The black dial hosts yellow gold toned indexes and hands. The watch is powered by a tough solar that does not require regular battery replacement. With the mobile link function using Bluetooth ®, the owner can not only display the correct time, but also easily set the alarm and world time from your smartphone.
