A. Lange & Söhne marks a milestone with the release of the Datograph Handwerkskunst, a masterful expression of the watchmaker’s art in celebration of the 25th anniversary of the renowned Datograph chronograph. Introduced in 1999, the Datograph has set standards in chronograph design and functionality.

The term ‘Handwerkskunst’, German for ‘artisanship’, defines a line of ultra-exclusive, limited-edition watches that A. Lange & Söhne has been offering since 2011. Notable predecessors include the Lange 1 Tourbillon Handwerkskunst and the 1815 Rattrapante Perpetual Calendar Handwerkskunst, which showcase exceptional artistic decoration on both dials and movements.

This latest creation features a 41 mm case made of 18kt yellow gold, beautifully framing a black-rhodiumed gold dial enhanced by light-grey rhodiumed totalizers. The dial boasts a distinctive tremblage engraving, achieved with a specially designed lining burin, a technique that ensures a fine-grained texture while maintaining the clarity of critical elements such as the arched brand logo and the tachymeter scale.
Further attention to detail is evident in the chamfered edges of the appliques and Roman numerals, and the straight grained hands and surfaces, highlighting the brand’s commitment to craftsmanship.
