A. Lange & Söhne Saxonia Datograph Perpetual 410.032E Rose Gold Silver Dial

Introduced in 2010, the Datograph Perpetual 410.032E is the Rose Gold, Silver dial version of A. Lange & Söhne's calendar chronograph, which joins the flyback and jumping minute counter of the 1999 Datograph with a perpetual calendar. The Datograph Perpetual calendar knows the length of every month, including leap years, and is displayed without disturbing the balance of the chronograph layout.

The Silver dial holds the day and month in subdials, the moon phase, a day/night aperture, the leap-year indication and the outsize date beneath 12 o'clock, together with the running seconds and 30-minute counter. The Rose Gold case is 41 mm across and 13.5 mm high, and its sapphire back reveals the hand-wound column-wheel movement, decorated by hand. It comes on alligator leather with a Rose Gold prong buckle, a warm setting for the Silver dial and its many indications.
