The multiple prizewinning design classic from Glashütte with a hand-wound caliber and patented power reserve indicator that reminds the wearer when to rewind the watch. German efficiency! Another NOMOS patent: the extra-large date. The date ring is set around the movement, while the power reserve mechanism is integrated into the mainspring barrel—so everything remains elegantly slender, despite the additional complications.
