This Lange 1 Anniversary Set is a set of two watches, intended to be worn and enjoyed as a pair. Created in honour of the 20th anniversary of the Lange 1, the pieces sport classic blue dials with guilloché patterns and are 38.5mm and 36.1mm, corresponding with the sizes of the Lange 1 and the Little Lange 1 respectively.

Both dials take inspiration from the famed Lange 1 reference 112.021, which was the first special edition piece released by A. Lange & Söhne, and also the first watch from the brand which featured a guilloché dial. The wave-style guilloché lends both pieces a depth that differs slightly from the usually restrained Lange 1 aesthetic.

More generally speaking, both watches bear the classic styling that has come to define the series, such as the asymmetric dial design and carefully designed date windows, which were inspired by the Five-Minute Clock at Semper Opera House in Dresden. Meanwhile, the applied indices and white-gold framed date-window provide a contrast against the blue dial, accompanied by matching white-printed lettering.

The Little Lange 1 is further distinguished by its diamond-set bezel, which is made up of 64 inlaid diamonds, and has a recessed corrector for changing the date compared to the larger pusher found on the Lange 1. Both are accompanied by deep blue alligator straps, but the Lange 1 strap features blue stitching, while the Little Lange 1 has a seamless strap.

Both watches are powered by the calibre L901.0, the original movement found within the Lange 1, and which can be seen through the sapphire caseback. The aesthetics of the movement are just as impressive as the mechanics, with chamfering and interior angles superbly hand finished. Moreover, it features an artistic flourish, a balance-cock engraved by one of Lange’s master engravers. In fact, each individual watchmaker's unique engraving style can be identified as a result. The bridges and plates are made from German silver, an alloy of copper, nickel and zinc, with a warm silver tone that will develop a subtle patina over time.

If sold within the United Kingdom, this A. Lange & Söhne Lange 1 20th Anniversary Set will be subject to 20% VAT.
