A rugged crown protector on the side of the face, Superluminova markings as well as a distinctive bezel of zirconia ceramic provide a robust visual impression. A screwed crown and the screwed steel back make it waterproof up to 20 bars. The watch is powered by a Swiss automatic movement whose elaborate, innovative mechanism causes the new hour digit to jump into the window exactly every 60 minutes. Domed sapphire glass covers the dial; the steel back is sealed with six screws.
