A. Lange & Söhne Saxonia Datograph Perpetual 410.136E Platinum Black Diamond Dial Limited Edition of 50 (2026)

Limited to 50 pieces, the Datograph Perpetual 410.136E marks twenty years since A. Lange & Söhne introduced the Datograph Perpetual in 2006, the first wristwatch to combine a chronograph, a perpetual calendar and Lange's outsize date. Presented in October 2026, it is the first Datograph Perpetual delivered on a metal bracelet, a newly designed five-row Platinum bracelet for the Datograph, with alternating brushed and polished links and a Platinum deployant buckle engraved with the Lange name.

The solid silver dial is finished in glossy Black and set with baguette-cut diamond hour markers, with silver-toned subdials for the day, month, leap year and the jumping 30-minute counter. Lange's outsize date sits at 12 o'clock above a blue moon-phase disc at 6 o'clock. The 41 mm Platinum case is 13.5 mm high, with a sapphire caseback showing the hand-wound movement of 556 parts.
