24 hours of inspiration. An infinite variety of perceptions. The DATOGRAPH UP/DOWN “Lumen” has more than one face. Changing with the light in the course of 24 hours, it reflects the vibrant atmosphere of every moment. From understated technicity through architectural elegance to a mysterious aura, it projects a captivating impression at any occasion – with a passion that never sleeps.
The DATOGRAPH UP/DOWN “Lumen” is the fourth model in a series of timepieces that make a bold design statement with the help of scientific knowledge. The three most prominent elements of its balanced face – the characteristic outsize date and the two subsidiary dials – form an equilateral triangle. At night, the luminous elements turn the distinctive design into an iconic beacon.
The DATOGRAPH UP/DOWN “Lumen” underlines the innovative power of A. Lange & Söhne in the development of pioneering chronographs. It combines the classic column-wheel design with a precisely jumping minute counter and a flyback function – mechanisms that are rarely found due to their complexity.
The harmonious architecture of the dial reflects the aesthetic equilibrium of the movement. The Lange outsize date and the two subsidiary dials for the seconds and the minute counter form an equilateral triangle.
This distinctive constellation already made the first DATOGRAPH, launched in 1999, a timeless fixed star. Due to its quintessential immaculacy in function and design, it enjoys cult status among purists, as does the DATOGRAPH UP/DOWN that was updated in 2012 with a power reserve of 60 hours and a power-reserve indicator.
The DATOGRAPH UP/DOWN “Lumen” takes the idea to the next level. Thanks to its semitransparent dial that exposes the ingenious disc ensemble of the outsize date and a luminous compound that causes all displays to glow in the dark, the iconic configuration unfolds a new aesthetic dimension.
