There are many German watch brands, and the number one is definitely A. Lange & Söhne. The well-known "German watch features": the three-quarter plate, the gold chatons and the gooseneck fine-tuner were all invented by A. Lange & Söhne. Ferdinando Adolph Lange & Söhne, the founder of A. Lange & Söhne, first studied watchmaking in Switzerland before returning to Glashütte and three other watchmakers to establish Glashütte as a centre for precision watchmaking. During World War II, the Soviet Union bombed the small town of Glashütte, destroying the Lange factory, and after World War II, Lange was confiscated by the East German government, and has been silent for 40 years. It was not until 1990 that Walter Lange & Söhne registered the new A. Lange & Söhne company, in which the LMH Group owned 90 percent of the shares, while A. Lange & Söhne owned only 10 percent. In 2000, Richemont acquired LMH, and in 2003 it bought the last shares in the Lange family.
 
The Lange & Söhne Revival was led by Walter Lange, but the soul was Günter Blümlein, who was highly regarded in the industry during the Günter period. In addition to Jaeger-LeCoultre and IWC, the giant Papi Studio has also contributed to the revival of A. Lange & Söhne, with the PLM tourbillon, which is the brainchild of A. Lange & Söhne.
 
The Lange 1 was the most important of the four watches launched by A. Lange & Söhne in 1994 and quickly became a masterpiece thanks to its asymmetrical dial and the first outsize date display. At the end of 2016, A. Lange & Söhne unveiled the new Lange 1, which combines the day and night display and the moon phase in the same subdial. It did not follow the trend of large watches, but chose to stick to the size of 38.5mm, which is more suitable for formal wear and can also take into account friends with thinner wrists. The new Lange January moon phase is available in three combinations – a platinum grey disc, a white gold black disc and a red gold white disc, with the white gold and black disc being more harmonious and more understated with the day and night display. The moon phase disc is linked to the second hand, and there is only a 24-hour error with the actual moon phase every 122.6 years. The Lange January Phase White and Rose Gold prices were only $316,000, while the platinum ash disc was $440,000.

In 2017, A. Lange & Söhne unveiled the Tourbograph Perpetual "Pour le Mérite", which combines five complications: a sesame chain drivetrain, a tourbillon, a chronograph, a split-seconds function and a perpetual calendar. The Arabic numerals on the dial, the minute scale on the train tracks, the blued steel hands, the rhodium-plated date hands in 18-carat yellow gold, and the trefoil-like arrangement of the subdials are all classic elements of Lange & Söhne pocket watches. Limited to 50 pieces, the tourbillon interacts the gravitational pull and the diminishing power of the hairspring, improving stability and precision.
