The **Lange 1 Daymatic** is a wristwatch by [[A. Lange & Söhne]].

In [[2010]] Lange presented this version of the classic [[A. Lange & Söhne Lange 1|Lange 1]], which was overwhelmed with prices, here equipped with [[self-winding]] movement.

Characteristic of all models of the type [[A. Lange & Söhne Lange 1|Lange 1]] is the design of the solid silver dials with asymmetric indications arrangement. The useful, patented [[big date]] indication improves the readability of the date compared to conventional timepieces approximately threefold.

The watch is equipped with the [[automatic]] [[manufacture movement]] [[Lange L021.1]], [[hacking seconds]], [[retrograde]] day of week indication and [[big date]]. The dial is made of solid silver; the hands are in [[gold]].
