Outsize date Since the re-establishment of the A. Lange & Söhne manufactory and presentation of its first new collection in 1994, there has been one complication that persistently characterises the design of many of our timepieces: the patented A. Lange & Söhne outsize date, which enables a date display with digits around three times as large as those in watches of comparable dimensions. 

The outsize date is made possible through two separate display surfaces: a ones disc with numbers 0 to 9 and an intersecting tens disc with numbers 1 to 3. The Lange outsize date draws its inspiration from the famous Five-Minute Clock in the Dresden Semper Opera House, which was engineered by the Dresden Court Clockmaker Johann Christian Friedrich Gutkaes. In 1838 he was commissioned to construct a clock that could be read easily, even from the back of the opera house.

The outsize date consists of two separate display elements: the ones disc and the intersecting tens disc
