A. Lange & Söhne Saxonia Datograph Perpetual Tourbillon 740.056FE White Gold Salmon Dial Limited Edition of 100 (2026)

Limited to 100 pieces and sold only through Lange boutiques, the Datograph Perpetual Tourbillon 740.056FE pairs a White Gold case with a dial cut from solid Rose Gold. Three major complications share the movement: a flyback chronograph, a perpetual calendar and a one-minute tourbillon with Lange's patented stop-seconds. The model was launched in 2016 in Platinum as the most complicated member of the Datograph line, and this White Gold edition followed in 2019.

Lange's outsize date sits at 12 o'clock, with the calendar spread across subdials for the day, month, leap year and moon phase, plus a day/night indicator and an arc-shaped power-reserve indicator near 9 o'clock. The Datograph minute counter jumps on the minute, as it has since 1999. The 41.5 mm White Gold case is 14.6 mm high over a hand-wound movement seen through sapphire. It wears brown alligator and a White Gold deployant buckle.
