Germany's A Lange & Söhne is known for its complicated watches. Of particular note is the Langematik Perpetual Calendar, launched in 2001. At that time, it was the first self-winding watch that combined a perpetual calendar and an outsized date display. The Sax-o-Mat movement is also equipped with a patented Zero-Reset mechanism that simplifies accurate time setting to the second: When the crown is pulled out, it stops the balance and advances the second hand to zero. The newest version has a white dial and is crafted in the firm's proprietary HoneyGold, which has only been used for specially selected limited editions and one-of-a-kind pieces, ensuring its exclusivity. A sapphire-crystal caseback enables viewing of the 478-part movement with hand-engraved 21K gold rotor and Lange-style three-quarter plate. The escapement and balance cock are manually hand finished and flawlessly engraved.

A Lange & Söhne showcases the supreme of German horology. Originally founded in 1845, the watchmaker persevered through Soviet nationalization, its trademark resurfacing in 1990 when it was realized and re-registered by Walter Lange. Early patrons and owners of its timepieces reflect the high regard in which the brand is held, having been worn by men of great prominence including the German Emperor Wilhelm II and Alexander II of Russia.Some of its most famous collections include the Lange 1 and Zeitwerk lines which assure the most intricate of assembly and finishing techniques, as well as carry the brand's distinctive outsize date which is three times the scope as those in watches of comparable dimensions. Recently sprung from the Zeitwerk family is the Minute Repeater piece which, melodically keeping time, is the first mechanical wristwatch to possess a jumping numeral display and decimal minute recurrence. The intricate ticking sounding from this timepiece mirrors the complexity of the watch itself, which is fashioned from 191 individually hand-finished fragments.
