**Langematik** is a [[self-winding]] watch by [[A. Lange & Söhne]].

===== History =====
After much success with their initial hand-winding models, A. Lange & Söhne launched an [[automatic]] movement in [[1997]]. The spectacular new [[manufacture]] [[movement]], the [[Lange L921.2|"Sax-O-Mat" L921.2]], features a [[micro rotor|3/4 rotor]] and unique [[hacking seconds]] with [[zero reset]]. This top-class watch received the maximum value of 6 stars during a test at the German watch magazine [[Chronos]].

The initial Langematik features similar styling to the [[A. Lange & Söhne Saxonia|Saxonia]], with baton markers, sword hands, and a classic round case. The Langematik was available either with or without the patented Lange "Big Date" window at 12 00. Models with the date complication used [[Lange L921.4|Cal. 921.4]] and had a slightly larger 37 mm diameter and 9.7 mm thick case. References included 308.021, 308.027, 308.031, and 308.032 in yellow gold/champagne, white gold/black, pink gold/black, and pink gold/silver combinations. Non-date models used a 36.8 mm diameter 8.2 mm thick case. These were produced in yellow gold/champagne dial (Ref. 301.021), white gold/black dial (Ref. 301.027), and platinum/rhodium dial (Ref. 351.025). All feature a sapphire case back.

A rare model was the [[2001]]-[[2004]] Langematik Anniversary Jubilee, Ref. 302.025. Inside the 37 mm platinum case was a special [[Lange L921|Cal. L921.7]] movement with a [[micro rotor|3/4 rotor]] with platinum mass for winding. The enamel dial features a red "XII" mark.

The Grand Langematik was introduced in [[2003]] and produced through [[2007]]. It shared the same Cal. L921.4 movement as the originial Langematik but had a larger 40.5 mm diameter, 10.7 mm thick case. References include the yellow gold/champagne 309.021, pink gold/black 309.031, and platinum/rhodium 309.025.

L922.1]] movement. Ref. 310.021 (310.221 with bracelet) has a yellow gold case and champagne dial, Ref. 310.032 (310.232 with bracelet) has a pink gold case and silver dial, Ref. 310.025 (310.225 with bracelet) has a platinum case and rhodium dial, Ref. 310.047 has a pink gold case and black dial, and Ref. 310.026 has a white gold and black dial.
