SIHH 2019: A. Lange & Söhne Langematik Perpetual Honey Gold

The perpetual's swan song?

A. Lange & Söhne first introduced its proprietary gold alloy back in 2010. Known as honey gold for its pale colour that’s a cross between rose and yellow gold, the metal was used solely for limited edition watches, which is exactly the case for the new 100-piece Langematik Perpetual.

First unveiled in 2001, the Langematik Perpetual was the first automatic wristwatch that paired a perpetual calendar with Lange’s signature outsize date. Though the Langematik Perpetual was once available in both platinum and the three colours of gold, it is now only available on honey gold.


The applied elements of the dial, namely the Roman numerals, hands and date window, are also made of solid honey gold.


Besides the material, there’s a key visual difference between the ordinary version and the honey gold edition: the chapter ring for the Roman numerals is decorated with a radial guilloche.

The rest of the watch is identical to the earlier versions of the Langematik Perpetual, with the case measuring 38.5mm by 10.2mm.


The L922.1 movement within is based on the venerable Sax-0-Mat movement. It is one of the earliest movements by Lange, but has withstood the test of time and is still found in several current watches.

Named after its hacking zero-reset seconds, the Sax-O-Mat movement has the best of both worlds by combining the ornate, relief cast 21k gold rotor with Lange’s signature three-quarter plate. With the rotor off-centre, the trademark engraved balance cock is always visible.


Hidden from view underneath the dial is the perpetual calendar module. The perpetual mechanism is of a traditional grand levier, or “big lever”, construction with the distinction of being paired with an outsize-date window. Setting the calendar can be done via pin pushers integrated into the side of the case.
