A. Lange & Söhne

With a second time zone and the motto "Born in Saxony, at home in the world", the

LANGE 1 TIME ZONE in 2005 wrote yet another chapter in the successful history of

A. Lange & Söhne. It began fourteen years ago when the LANGE 1 had its debut. In

the meantime, the watch with the unusual face has become the symbol for the

comeback of an eminent brand rooted in Saxony: A. Lange & Söhne. Its off-centre dial

layout, the twin mainspring barrel with a power reserve of three days, and the first

outsize date in a regularly produced wristwatch inspired an entire industry. And its

exquisitely crafted movement delivered proof that precision watchmaking had finally

rediscovered its second home outside Switzerland.

All these features are embodied in the LANGE 1 TIME ZONE – complemented with an

easily adjustable display of the hour in a second time zone. Unlike other watches with a

second time zone, it offers a further genuine benefit: an ingenious adjustment

mechanism makes it possible to conveniently swap the home time displayed on the

large dial and the zone time indicated on the subsidiary dial. As an alternative to the

original combination of an 18-carat pink-gold case with a bright argenté dial, the solidsilver

dial is now also available in distinguished grey.

A closer look reveals a second, rather exotic change: A South American president

turned the hands of the clock and gave his country a new time zone. His decision to

move the time in Venezuela back by half an hour (UTC–4:30) disqualified Caracas as

the reference city for Atlantic Standard Time (UTC–4). This role has now been

assumed by Santiago de Chile. The "CARACAS" on city rings – and this applies to all

siblings in the LANGE 1 TIME ZONE family – will henceforth be replaced by

"SANTIAGO".
