A. Lange & Söhne 1815 Rattrapante Perpetual Calendar 421.032FE Rose Gold Silver Dial (2026)

In Rose Gold, the 1815 Rattrapante Perpetual Calendar 421.032FE is one of the two founding versions of the model A. Lange & Söhne launched in 2013, alongside the Platinum 421.025FE. It lets the wearer time two events at once with the split-seconds hand, while the calendar handles months of different lengths and leap years on its own until 1 March 2100, keeping the Lange pocket-watch order of displays on an 1815 dial.

The Silver dial of solid silver shows day and date at left, month and leap year at right, and the moon phase with small seconds at 6 o'clock, together with a power-reserve indicator. Rose Gold and blued steel hands read against it. The Rose Gold case measures 41.9 mm by 14.7 mm and is worn on an alligator strap with a Rose Gold deployant buckle, with the movement on view through sapphire.
