With their cutting-edge technology, combined with the prominence of the dial and the calibre design, the DATOGRAPH models epitomise a separate category of mechanical chronographs. The outsize date and the two subsidiary dials form an equilateral triangle; this endows the face with balanced poise and assures excellent legibility. The DATOGRAPH UP/DOWN has a power reserve of 60 hours; the state of wind is easily readable on the UP/DOWN display.

The distinctive arrangement of the displays calls for unusually long and slender levers in the movement – plus the in-depth know-how and skills of the designers. This horological opus reveals its particular charm especially when the chronograph mechanism is activated, triggering the ingeniously orchestrated interaction of levers, rockers, and wheels.
