A. Lange & Söhne – Saxonia Datograph Perpetual Chronograph NEW

DATOGRAPH PERPETUAL
Chronograph and perpetual calendar with a noble 
white-gold/grey contrast

The pairing of a solid white-gold case with a grey dial adds elegance and charisma to the combination of a flyback chronograph with a perpetual calendar.

For French writer and Nobel laureate André Gide, grey was the colour of truth, which might be due to its counterbalancing effect and the seductive radiance of this hue. In the DATOGRAPH PERPETUAL, the juxtaposition of a white-gold case and a grey dial accommo-dates both of these aspects. Since 2006, its name has been a synonym for the ingenious combination of a flyback chronograph and a perpetual calendar.

With three highly elaborate, technically advanced mechanisms, it fully lives up to the task of precise short-time measurements: The column-wheel concept assures dependable control of all chronograph functions, the jumping minute counter always delivers distinct legibility of stopped times and the flyback system makes it possible to accurately measure the durations of events in quick succession.

With its Lange outsize date, day of week, month and leap year indications, the perpetual calendar is so precise that it requires no adjustment until the year 2100, when a one-day correction is needed. All calendar displays can be advanced simultaneously with a convenient rapid-correction pusher. Additionally, three recessed correctors allow the displays to be adjusted separately.

The dark grey hue of the dial clearly emphasises the displays and prominently showcases the deep blue lunar disc with its golden stars. Baton hour markers as well as hour and minute hands in rhodiumed gold highlight the rich-contrast design that was first introduced with the 2010 launch of the pink-gold version. The chronograph hand indicates the stopped time to one-fifth of a second. It is made of blued steel.

The same material was chosen for the minute counter and seconds hands, allowing them to stand out prominently against the bright rhodié background of the subsidiary dials.

With its movement consisting of 556 lavishly finished parts, it delivers fresh proof of the Saxon manufactory’s virtuosity in the realm of horological complications.
