A. Lange & Söhne Saxonia Langematik Perpetual 310.032E Rose Gold Silver Dial (2026)

When A. Lange & Söhne launched the Langematik Perpetual in 2001, it was the first mechanical wristwatch to combine a perpetual calendar with the Lange outsize date. The Rose Gold 310.032E, introduced in 2007, keeps that self-winding design and Lange's patented ZERO-RESET, which returns the seconds hand to zero when the crown is pulled. The calendar needs no manual correction until 2100. Its three-quarter rotor of gold with a Platinum mass winds the movement as it is worn.

On the Silver dial of solid silver, Rose Gold Roman numerals and lancet hands frame the outsize date in the upper half, with subdials for the day of the week, the month with leap year, a 24-hour display with day/night indicator, and the small seconds with moon phase at 6 o'clock, while a main pusher on the case advances every calendar display at once. The 38.5 mm Rose Gold case is 10.2 mm high, on alligator with a Rose Gold prong buckle.
