A. Lange Soehne LANGE 1 25th Anniversary

A. Lange & Söhne LANGE 1 “25th Anniversary” – a photographic presentation

Reading Time: 3 minutes

LANGE 1 was one of the four watches that A. Lange & Söhne presented on 24th of October 1994. An important date in the German’s watchmaking history and one of the most important milestones for the brand. Walter Lange and his partner Günter Blümlein made history that day. This year, A. Lange & Söhne celebrates 25 years from that moment with special anniversary pieces. The A. Lange & Söhne LANGE 1 “25th Anniversary” is one of them. It was presented at SIHH 2019, where I was able to have it in my hands. Since rivers of ink were spilt and an unnumbered amount of bytes have travelled on the Internet, I will restrain myself from praising once again the LANGE 1 and the prominent German brand. Certain is the level of watchmaking presented by A. Lange & Söhne is high. Very high! The amount and level of finishes are ones of the best available. Of course, the LANGE 1 “25th Anniversary” makes no exception.

I will present to you my favourite angles. The entire gallery is available at the end of the article, after the technical specification paragraph.

Lange 1 face
A watch that made history, the Lange 1 was and still is a very desirable watch.
Lange 1 dial
With a layout characteristic to the German brand, the A. Lange Soehne LANGE 1 25th Anniversary is easily recognisable
A. Lange Soehne LANGE 1 25th Anniversary time sub-dial
The time display is the main element of the dial having the most generous dimensions from the dial’s elements
Date window
The big date aperture is highlighted by a beautiful white gold frame
Lange 1 small seconds
The third element of the asymmetric arrangement is the small seconds’ indication.
Lange 1 power reserve
The power reserve enriches a space that would otherwise look empty.

Please note the elegant lance hands that are hand manufactured and finished.

Lange 1 caseback
The case back is covered by a hunter caseback. An elegant engraving is present.

Note the Walter Lange and Günter Blümlein mention. An ode to two special persons. One of them, Günter Blümlein shaped the world of watches. Besides A. Lange & Söhne, Jaeger-LeCoultre and IWC have flourished with him in charge. Without him, the mechanical horological world would have been sad and empty.

Calibre L121.1
Under the hunter caseback, the fabulous Lange manufacture calibre L121.1.
Lange 1 balance cock
The charming balance cock with hand-engraved motifs and the number “25”
Lange 1 on the wrist
Could someone deny the beauty of the Lange 1? Here on the wrist, during SIHH 2019.

Some notes will be available in the gallery. Enjoy!
