The G-Shock GW-4000-1A Black aviation watch looks like a lot of bells and whistles, because it is. By wrapping an alpha-gel belt around the module as well as adding a layer underneath it and by employing aluminum washers and oiled o-rings beneath the screw heads that secure the band to the case, the GW-4000-1A Black Aviation watch from G-Shock is now more resistant than ever to shock, vibration and centrifugal force.
