A polished stainless steel case, a dial in deep, glossy blue, complemented by beautifully contrasting hour and minute numerals. Tetra neomatik blue has a striking impact with its 33 x 33 millimeter dial and high color intensity. The richly embellished NOMOS DUW 3001 caliber ticks with efficient neomatik technology. The three-quarter plates, ribbing and tempered blue screws can be seen through the sapphire crystal back—the famous hallmarks of Glashütte’s 175 years of watchmaking. The limited engraving on the case back indicates the exclusivity of this watch.
