Casio G-Shock G-Steel Watch GSTB100D-1A

From G-SHOCK, the watch that always strives for toughness, the first G-STEEL lineup models to offer chronograph performance in analogue format.

A new layer guard structure houses resin cushioning parts inside the case, for a more elegant design and a better fit to the wrist. High density mounting technology makes it possible to create a module that is smaller and thinner, which also contributes to a better fit. These watches are equipped with Bluetooth that lets them connect with a smartphone at the press of a button, and acquire time information from an internet server.
