What makes the A. Lange & Söhne Zeitwerk replica so special in the A. Lange & Söhne collection? Is it the technology? Well, of course it has something special hidden in its movement, but so does the Richard Lange Perpetual Calendar Terraluna for example. Is it its design or its case? What is it then? Well, simply its display and the way it tells and sings time, something that could have been expected from a bold, unchained, independent watchmaker but not from an ultra-serious and traditionalist manufacture like A. Lange & Söhne. The Zeitwerk is a surprise, mostly because who created it rather than what it really is.Not really, as clearly, it has many of the elements that compose a A. Lange & Söhne. Is it the quality, the finishing, the execution? Neither, as the Zeitwerk is a true masterpiece, like all of the other watches from Lange – and it is finished with the most precautious attentions.
Then, as we told you, it was a surprising watch because of the brand which introduced it. You have to understand that A. Lange & Söhne is not MB&F or URWERK. They were used to create watches with normal hands, with classical display, with understated look and with great simplicity and elegance. It’s German watchmaking. However, with this unique display, the Zeitwerk created huge discussions and loud reactions – that, besides being loud, were also astonished… Why that? Well, after the first perplexed moments, you clearly see the raison d’être of the Zeitwerk, its link with the rest of the A. Lange & Sohne Zeitwerk Striking Time copy watches, its integration in the family.The very first A. Lange & Söhne Zeitwerk has been introduced at the SIHH 2009 – you can see an example of this early and non-chiming Zeitwerk here. It has been a surprise for two reasons. First because of its display, that tells time via three instantaneously jumping discs, using a complex constant force mechanism and an innovative way to distribute the energy of the movement to the display.
For many reasons, the Zeitwerk is strange and at the same time, it features many of iconic elements of the Saxonian manufacture: the use of oversized discs, a clear display, the management of energy and an overall look that is certainly in the vein of Lange’s DNA. We reviewed many watches from A. Lange & Söhne (the Lange 1, the Datograph, the Double Split or the 1815 Chronograph) and for this reason, it makes sense for us to have a deeper look at this special watch, the A. Lange & Söhne Zeitwerk Striking Time.
The use of a constant escapement allows the jump of 3 discs instantaneously, right? Without making any changes to the mainspring, to the remontoire or to the escapement, this movement still have enough power stored to actuate a strike train. Impressive! By using the same base movement and adding a striking function (located on the dial side, at 6), the Zeitwerk Striking Time keeps the same 36 hours power reserve. These extra reserves of energy are used by the chiming mechanism to tension the springs that actuate the two hammers. With the normal Zeitwerk, A. Lange & Sohne watch replica did already quite an impressive job to manage the energy.
