A. Lange & Söhne – DATOGRAPH Up/Down in Pink Gold NEW

Launched in 2012, the DATOGRAPH UP/DOWN is endowed with milestone technical features: A classic column-wheel control mechanism, a precisely jumping minute counter and a flyback function come together in a movement that showcases true engineering finesse.

The aesthetic quality of the calibre is reflected by the balanced dial layout with the characteristic Lange outsize date and the two argenté subsidiary dials for the seconds and the minute counter forming an equilateral triangle.

The UP/DOWN attribute is standard Lange terminology for the power-reserve indicator. UP stands for the maximum power reserve of 60 hours when fully wound, while DOWN means that the energy of the mainspring has been depleted and the pink-gold arrow enters the red zone of the indicator.

The black dial made of solid silver is embedded in an 18-carat pink-gold case with a diameter of 41.0 millimetres. Luminous hands and pink-gold baton hour markers accentuate the systematic design concept.

The sapphire-crystal caseback allows many components to be observed in action, for instance those of the precisely jumping minute counter, which assures precise time measurement, or the column wheel that controls the chronograph functions.

Composed of 451 parts, the L951.6 manufacture calibre unites all typical Lange quality hallmarks, such as the sturdy three-quarter plate made of untreated German silver, lavishly finished movement parts, a hand-engraved balance cock and four gold chatons secured with screws.
