Dornblüth & Sohn World Time Auf & Ab Silver Dial
The World Time Auf & Ab (up and down) power reserve collection showcases the second time zone in the sub dial at 6 o’clock by bringing the second hand to the centre. The result is an exceptionally clean look with extra functionality. This is a favourite among savvy business travellers where looks and individuality count.
