A. Lange & Söhne Marks 20 Years of the Datograph Perpetual in Platinum
Eleven hand-applied diamond markers bring a sharper jewelry-focused edge to the black-dial chronograph.
Summary
A. Lange & Söhne marks 20 years of the Datograph Perpetual with a new platinum edition.
The black dial features 11 baguette-cut diamond hour markers.
Its hand-wound L952.1 calibre combines flyback chronograph and perpetual calendar functions.
To celebrate the 20th anniversary of the Datograph Perpetual, A. Lange & Söhne has introduced a highly exclusive 50-piece limited-edition update to the iconic grand complication model. First launched in 2006, the Datograph Perpetual was the brand’s first wristwatch to seamlessly integrate a classic column-wheel flyback chronograph with a mechanical perpetual calendar and an outsize date.
This new iteration elevates the original design by pairing a 41mm 950 platinum case and matching platinum bracelet with a striking black and rhodié-colored 925 silver dial. Further enhancing its prestige, the dial features eleven manually applied baguette-cut diamonds serving as hour markers, omitting indices at 4 and 8 o’clock to accommodate the prominent rhodié auxiliary dials.
The dial is anchored by the signature Lange outsize date at 12 o’clock, which forms the tip of an equilateral triangle with the two main subdials. The subdial at 9 o’clock tracks small seconds, the day of the week, and a day/night indicator, while the 3 o’clock subdial displays the jumping minute counter, the month, and the leap-year cycle. A precise moon-phase display sits at 6 o’clock, completing the triangle.
The perpetual calendar mechanism is programmed to remain accurate until March 2100, while the moon phase will deviate by a single day only after 122.6 years of continuous operation. Adjusting these displays is remarkably simple, utilizing a single rapid-correction pusher at 10 o’clock or individual recessed correctors.
Driving these dual complications is the meticulously crafted L952.1 manually wound manufacture caliber, visible through a sapphire-crystal caseback. Assembled twice by hand, the 556-part movement features plates and bridges made of untreated German silver, a hand-engraved balance cock, and a classic column wheel to coordinate the chronograph’s precise switching sequences. The complex architecture provides 36 hours of power reserve while operating at a frequency of 18,000 semi-oscillations per hour.
