Description

The present reference is the A. Lange & Söhne Zeitwerk Date ref. 142.031 (LSLS1424AG), a virtuoso achievement in modern Saxon haute horlogerie that pairs the manufacture’s iconic digital jumping-numerals display with an ingenious glass peripheral date.

Housed in an 18k pink gold case, the watch measures 41.9 mm in diameter and 12.2 mm in thickness, showcasing the brand’s signature three-part construction with finely brushed casebands, polished stepped bezels, and prominent, sculpted lugs. The case features a sapphire crystal caseback and is water-resistant to 3 bar (30 metres).

The deep black dial is dominated by the German silver time bridge, which frames the large, jumping numeral apertures for the digital display of hours and minutes. At 12 o’clock, an up/down (Auf/Ab) power-reserve indicator tracks the movement’s running autonomy, balanced by a recessed small seconds sub-dial at 6 o’clock. Circumscribing the dial’s perimeter is an innovative date ring made of frosted glass featuring numerals 1 through 31; a small red segment positioned beneath the ring jumps forward precisely at midnight, highlighting the current date in vivid red without disrupting the dial’s clean architecture.

Powering this mechanical masterpiece is the manufacture manually wound Calibre L043.6, composed of 451 components. Operating at an unhurried frequency of 18,000 semi-oscillations per hour (2.5 Hz), it delivers an impressive 72-hour power reserve. The movement is equipped with a patented constant-force escapement between the barrel and the jumping numerals mechanism, which delivers a uniform impulse to the balance wheel while releasing the tremendous burst of energy required to jump the numeral discs instantaneously every minute. The calibre is finished to Lange’s uncompromising standards, featuring untreated German silver plates and bridges, screwed gold chatons, blued screws, and a hand-engraved balance cock.

The timepiece is fitted with a hand-stitched black alligator leather strap, secured by an 18k pink gold prong buckle. Uniting mechanical ingenuity with the unmistakable aesthetic clarity of Glashütte watchmaking, this Zeitwerk Date in pink gold stands as one of the most distinctive and technically compelling creations in contemporary horology.

A.Lange & Sohne – bio

Founded in 1845 by Ferdinand Adolph Lange in Glashütte, Germany.  The company soon became the pioneers in watchmaking in their region.  After Ferdinand’s death his sons, Emil and Richard continued to produce the finest pocket watches of their time.
During World War II, they were victims of bombardments and eventually even got nationalised by the Soviet administration and ceased to exist. At the fall of the Berlin wall in 1990, the grand son of the founder, Walter Lange, revived the company with the help of Swiss watch manufacturers such as IWC & Jaeger-LeCoultre.   The brand introduced their new collection in 1994 with success and by 2000 the company got acquired by the Richemont Group.
