Nomos Glashutte Watch Tangente 2Date Blue 136.SB. Leading the way: Two markers frame the current day on the NOMOS ring date. On the deep blue dial with silver-colored numerals and indexes, they are white just like the date in the additional window at 6 o'clock. The dual date display shows the big picture while keeping track of the details. Tangente 2date is the first hand-wound model to feature the exclusive ring date. And is somewhat more compact than the neomatik update model: the case diameter is 37.5 millimetres.
