Produced in a limited edition of just 30 examples in 2012, the Lange Zeitwerk Handwerkskunst is the rarest of all of Lange’s coveted Zeitwerk models. The first time ever appearing at auction, it’s distinguished by a meticulously crafted dial, made of white gold and hand engraved with a grained texture known as “tremblage”. The resulting surface is sumptuous and exquisite, and the product of two weeks of labor. Its heavy platinum case, measuring a masculine 41.9 mm in diameter, shines with highly polished lugs and a brushed-finished central case band. The Lange caliber L043.1 within is specially finished with a granular surface treatment, and all writing on the movement is hand engraved, further demonstrating the importance of this exceptional timepiece. In immaculate condition, this example includes its original boxes, leather folio, and guarantee papers.
