This Lange 1 commemorative edition is going places.

Oh Lange, what have you done to us? Now we are starting to mark the passing months with your watches. If you don’t already know, A. Lange & Söhne is celebrating the 25th anniversary of its most iconic collection, the Lange 1, by releasing one new limited edition every month - all the way until 24 October 2019, the same day that Walter Lange and Günter Blümlein relaunched the brand with the Lange 1 25 years ago.

For the month of May, the GMT complication takes the spotlight with the A. Lange & Söhne Lange 1 Time Zone ‘25th Anniversary’. Introduced 14 years ago, the Lange 1 Time Zone is easily one of the most regal and practical dual-time watches in modern watchmaking.

Here, the Lange 1’s famous two off-centered sub-dials are utitlised to display home and away times, at nine and four o’clock, respectively, complemented by day-night indicators for each. As with all Lange complications, the GMT function is easy to use. A pusher at eight advances the city ring, which displays the names of 24 world cities that correspond to 24 different time zones. (A tiny arrow at the 4:30 position of the smaller sub-dial points to the city of the second time zone.)

In the A. Lange & Söhne Lange 1 Time Zone ‘25th Anniversary’, all the famed GMT features and aesthetic sophistication of the previous models - available in platinum, pink or white gold – remain unchanged, as is the hand-wound Calibre L031.1 that has powered the series since its inception.

However, as it has become de rigueur for all Lange 1 ‘25th Anniversary’ editions, there are elevated decorative touches as well as the now-familiar combination of white gold case, sliver argenté dial and blue accents to mark the exclusive series. Another exclusive design hallmark is the engraved balance cock with blue Arabesque swirls and the number ’25’ that matches those on the outsize date.

As the fifth limited edition of the Lange 1 commemorative collection, the A. Lange & Söhne Lange 1 Time Zone ‘25th Anniversary’ ranks as the most practical, especially for frequent flyers. And like the previous anniversary models – with the exception of the Lange 1 ‘25th Anniversary’ that is capped at 250 pieces - this one is limited to 25 pieces.
