A. Lange & Söhne Lange 1 Moon Phase
Oh yes, another pre-SIHH introduction: the new A. Lange & Söhne Lange 1 Moon Phase is here ladies and gents. A welcome watch, as is any other Lange in my eyes. I like the fact that the brand stays fairly true to its values and – in comparison to other brands – keeps it classy. So, 14 years after the introduction, we are welcomed with a new Moon Phase in the Lange 1 series.

Lovely Moon – Lovely Lange
If Lange & Söhne creates a timepiece, I will not argue with you about the quality – since Lange & Söhne timepieces are respected in their category. I will however question the added value of a new timepiece. I have a small problem with a Lange timepiece, that can be found in the fact that they share a lot of characteristics.

Each Lange timepiece has its own charm and is – in one way or another – an added value to the brand. But in my honest opinion there’s too much of the same at moments. Is this bad? That’s up to you. I know it’ll probably sound strange, but I have no problems with this. In the end that is. Why? Because I like every Lange timepiece. No matter what model, or how much it looks like its little brother.

Fancy moon phase
Lange did – as increasingly more brands do – their utmost best to create something special of the moon phase in their watch. We’ve seen 3-dimensional moons, moon phases that look like a devil’s face and complete dials that function like a celestial instrument. Anyhow, A. Lange & Söhne did create a far less crazy moon phase, but that doesn’t mean less cool. It exists out of two solid gold moons twirling around the dial in front of a solid gold celestial disk. That, of course, performs one revolution every 24 hours. As a result you get a very good looking moon phase. A clear blue sky at day and a sky full of stars at night.

Follow the Lange 1
Following up the new Lange 1, this Moon Phase also has a new calibre; the L121.3 calibre. Introduced firstly two years ago in the Lange 1. The moon phase function with its 70 components is very cleverly placed on the L121.3 calibre, making it only a fraction larger than the L121.1 calibre as found in the Lange 1.

Cool facts of course and a movement one should demand from a brand as A. Lange & Söhne. I think people are mostly interested in the fact that the Moon Phase is finally revisited and it looks as stunning as ever. I am very interested in the watch, but as I said before it looks a lot like a Lange we all know. But, since I also said this before.. Judge for yourself if you like it or not. Don’t shoot the Messenger.
