The unique 3-D design of these watches creates the appearance as if they have been chiseled out of stone, creating a look of toughness and solid power. Their concave dials with half-gloss finish casts a menacing shadow over their dials and combined with the case and band's matte finish (GA150MF-1/7) or metallic colorway (GA150MF-8) give them an edgy, streetwise look. Black resin band analog & digital watch with a metallic grey face.
