A. LANGE & SÖHNE: A Legacy of Precision
The A. LANGE & SÖHNE brand has built its reputation on chronometric precision and hand-finished movements since its founding. The manufacture’s approach to watchmaking—from hand-engraved balance cocks to hand-assembled escapements—distinguishes it in the horological world. The DATOGRAPH UP/DOWN exemplifies this commitment, introducing a decimal-based power reserve display that redefined how collectors read remaining barrel energy.
Celebrating 25 Years of the DATOGRAPH
To mark the 25th anniversary of the iconic DATOGRAPH, A. LANGE & SÖHNE presents a watch that unites traditional Saxonian case finishing with contemporary decimal functionality. The DATOGRAPH UP/DOWN appears in white gold with a blue dial, positioning it as a statement piece within any serious collection.
A Closer Look at the Design
The DATOGRAPH UP/DOWN employs a white gold case with soft-iron inner case for magnetic shielding. The blue dial displays applied gold indices and counter rings whose finish matches the case metal. The three chronograph subdials—running seconds, elapsed minutes, and the signature decimal power reserve—occupy specific positions that follow the original 1999 architecture. Finishing extends to the caseback, where the caliber movement remains visible through a sapphire display window.
Technical Excellence
The watch houses the L951.1 movement, a column-wheel chronograph caliber with flyback function. The UP/DOWN mechanism is the hallmark feature: rather than a traditional power reserve arc, a vertical hand reads remaining energy across a 120-hour (five-day) scale printed in tenths. This decimal display permits precise energy accounting—critical for collectors who maintain multiple watches. The movement operates at 4 Hz and contains 441 components, with finishing spanning perlage, polished steel parts, and hand-engraved components consistent with the brand’s three-quarter plate construction.
