A. Lange & Söhne Unveils The Zeitwerk Date In Pink Gold

The A. Lange & Söhne Zeitwerk Date in pink gold German watchmaker, A. Lange & Söhne, unveiled the latest version of Zeitwerk Date. It is the first model in the collection that combines a pink gold case with a gray dial. The Zeitwerk collection was introduced in 2009 with a 'switching digital time display' powered by an innovative mechanical movement. In addition to the jumping numerals mechanism, the Zeitwerk Date introduced in 2019 added an equally innovative date ring, circling the dial. Made of printed glass, it depicts the numbers 1 to 31. A small color segment on a ring beneath the date ring moves one step at midnight, allowing the current date to appear in red. It moves one full revolution each month. The date is corrected with a pusher at 8 o'clock. A view of the A. Lange & Söhne Zeitwerk Date in-house caliber L043.8 Six years after making its debut in white gold, the Zeitwerk Date is now available in 750 pink gold. It's a subtle change for sure. Both versions of the 44.2mm case house a 925 gray silver dial with a well-balanced display. Two apertures for the prominent hour and minute numerals are arranged from left to right on the center axis of the dial. Within a fraction of a second, the patented jumping numerals mechanism switches the numeral discs 1,440 times each day. The hour display can be advanced separately with the pusher at 4 o'clock. To enable the correction independently of the switching cycles of the movement, a clutch uncouples the hour ring from the jumping numerals mechanism with every actuation of the pusher. Like the date function, the switching impulse is generated when the pusher is released. The top of the dial is the 'UP/DOWN' power reserve indicator and at 6 o'clock is a seconds subdial. The German silver time bridge is part of the movement and frames the time indication with the subsidiary seconds dial, thus creating an instantly noticeable connection between the aesthetic appeal of the exterior and the interior mechanics. The A. Lange & Söhne Zeitwerk Date Controlled by a patented constant-force escapement, the force needed to advance the time indication is delivered by a twin mainspring barrel. A fly governor absorbs the surplus energy and protects the jumping numerals mechanism. Every 60 seconds, the constant-force escapement provides the switching impulse for the numeral discs. Positioned between mainspring barrel and balance wheel, it provides stability by assuring that the balance is powered with a consistent amount of force across the entire power-reserve duration. 'The Zeitwerk Date gives traditional A. Lange & Söhne watchmaking artistry a distinctive, contemporary face,' Anthony de Haas, director of Product Development said in a statement. 'Precisely at midnight, it puts on an exceptional show. Because then, all three jumping numeral discs and the date ring switch simultaneously. At that moment, a force and precision are at work that you imagine can be felt through the case.' The watch is powered by the in-house caliber L043.8, beats at a frequency of 18,000 semi-oscillations per hour (2.5 hertz). The manually wound caliber with its twin barrel and two mainsprings provides a 72-hour power reserve. The sapphire-crystal caseback of the pink-gold case provides a view of the artisanal finish of the 516-part movement. Technical and aesthetic highlights include the ratchet wheel adorned with solarization and engraved with the brand name, as well as the constant-force escapement bridge.
