About the A. Lange & Söhne Zeitwerk
Founded in Glashütte, Saxony in 1845 by Ferdinand Adolph Lange and revived in 1990 after German reunification, A. Lange & Söhne produces entirely in-house movements finished to the exacting Glashütte tradition, characterized by three-quarter plates in German silver, hand-engraved balance cocks, and beveled, blued screws. The Zeitwerk, introduced in 2009, was a landmark achievement because it solved the mechanical problem of advancing jumping numerals — which demand a sudden burst of energy — while maintaining consistent mainspring tension through a patented constant-force escapement, ensuring accuracy is never compromised at the moment of the jump. The collection spans three distinct complication levels: the base Zeitwerk with jumping hours and minutes, the Zeitwerk Striking Time which audibly chimes the displayed time at the push of a pusher, and the Zeitwerk Minute Repeater which sounds hours, quarter hours, and minutes on demand — all housed in precious metal cases of white gold, rose gold, or platinum.
What to Look For
Buyers comparing Zeitwerk references should note that case size correlates directly with complication level — the foundational models run 41.9mm in references such as 140.029, 140.032, 142.025, and 142.031, while the Striking Time and Minute Repeater variants step up to 44.2mm to accommodate their additional mechanisms, as seen in references 145.029, 145.032, and 147.028F. Case metal and dial color meaningfully affect both aesthetics and secondary-market value, with platinum examples historically commanding a premium over gold, and limited dial colors such as blue on the Minute Repeater 147.028F making those pieces particularly sought after by collectors.
Frequently Asked Questions
Are the A. Lange & Söhne Zeitwerk watches at Bizak and Co. new or pre-owned?
The majority of Zeitwerk pieces listed in this collection are brand new, as indicated on each product listing, and all are authenticated by Bizak and Co. before shipping. Pre-owned examples, where listed, are also fully authenticated and described accurately by reference number and condition.
What is the difference between the Zeitwerk Striking Time and the Zeitwerk Minute Repeater?
The Zeitwerk Striking Time, references 145.029 and 145.032, uses a pusher to audibly strike the time displayed on the digital disc display, giving an instant readout in sound at the wearer's request. The Zeitwerk Minute Repeater, reference 147.028F, goes further by chiming hours, quarter hours, and minutes in the classical repeater tradition, representing a higher level of acoustic and mechanical complexity and commanding a correspondingly higher position in the collection.
Which Zeitwerk reference should I consider if I want platinum?
The Zeitwerk Platinum 142.025 with its rhodié silver dial is the platinum configuration available in this collection, offering the prestige of the rarest case metal in the 41.9mm standard Zeitwerk format. Platinum Lange pieces are produced in smaller quantities than gold variants and are generally considered the most collectible configurations within any given reference family.
