In 2023, A. Lange & Söhne updates its ZEITWERK timepiece, with two new versions of this award-winning mechanical digital watch, in platinum and pink gold.
First released in 2009, the ZEITWERK is notable with its large jumping numerals for the hours and minutes, with a constant-force escapement as a beat controller.
In the new versions, the evolved calibre L043.6 inside provides a power reserve doubled to 72 hours, offering even greater convenience. The movement features an oscillation system with its own balance spring and patented beat-adjustment system. It oscillates with a frequency of 18,000 semi-oscillations per hour (2.5 hertz).
The time bridge on the dial has been subtly reworked to make more room for the subsidiary seconds dial at six o’clock. In the scale of the power-reserve indicator on the opposite side, harmoniously positioned above the round of the time bridge, the last twelve hours are now marked in red to clearly indicate that the tension of the mainsprings is gradually waning.
The sapphire bearing jewel for the ones- and tens-minute ring to the left of the two indications is a refined detail that also builds a bridge to the movement. In most cases, rubies are used for bearing jewels, but in this case, Lange’s watchmakers chose this colourless, transparent precious stone for aesthetic reasons.
The new ZEITWERK has a case diameter of 41.9 millimetres and a height of 12.2 millimetres. It is available in two versions. It comes in pink gold with a black dial and a time bridge made of untreated German silver. The platinum edition has a rhodié dial made of solid silver. The time bridge is black rhodiumed. Colour-matched hands round out the harmonious design. The pink-gold model has a black alligator leather strap while the platinum version is paired with a dark-brown alligator leather strap.
