A. Lange & Söhne Saxonia watches

The A. Lange & Söhne Saxonia is the Glashütte maker's family of round gold dress watches, named after Saxony, the German state in which Glashütte lies. It was one of the four models Lange presented in Dresden on 24 October 1994, with the Lange 1, the Arkade and the Tourbillon Pour le Mérite: the first watches after Walter Lange and Günter Blümlein refounded the company in 1990.

The 1994 original, the yellow gold 102.002, set the pattern: the hand-wound calibre L941.3, a large date at 12 o'clock balanced by small seconds at 6, and applied rhombus-shaped markers instead of numerals. Lange reworked the line at SIHH 2011 with new calibres and longer gold markers set closer to the edge of the dial, and added the Thin, the Automatik and the Dual Time.

The Thin shows hours and minutes only. Its case is 5.9 mm thick around the hand-wound L093.1, a movement 2.9 mm high with a 72-hour power reserve, built the Glashütte way with a German silver three-quarter plate, screwed gold chatons and a hand-engraved balance cock. It began at 40 mm and gained a 37 mm version in 2016; the 2018 white gold Thin with a copper-blue aventurine dial (205.086) measures 39 by 6.2 mm. The Saxonia 35 and the 34 mm Kleine Saxonia are the smaller versions of the plain Saxonia.

The Moon Phase brings back the 1994 large date at 12 and adds a solid gold moon disc cut with 852 stars, accurate to one day in 122.6 years, on the automatic L086.5. The Dual Time adds a second time zone with a 24-hour day-night indicator on the automatic L086.2. The Annual Calendar of 2010, the line's first complication, follows the different month lengths but not leap years. Alongside the Saxonia sit Lange's bigger complications: the Datograph chronograph with its Up/Down and Perpetual versions, the Double Split of 2004, and the Triple Split of 2018, which adds a third split-seconds hand and can time two events of up to 12 hours.
