I wrote about the Zeitwerk Minute Repeater that the watch was expected. It is not the same with this new Lange One at least for me. I was honestly surprised to discover a new version of the "classic" Lange One with its usual case diameter: 38,5mm. Of course, we all knew that the precisely jumping date system in place with the Lange One Tourbillon PC would not only stay with this watch and that it would be deployed in other watches of the collection.
Actually, if when it comes to the pure point of view of the design, the new Lange One are very similar to the previous ones, the lay-out of the movement L121.1 is totally different from the one of the L901.0. It is a big surprise since the dial is organized the same way. But when you turn over the watch... you seem to discover a totally new piece!
Here is the new movement:
And here is the former one:
The balance wheel of the new movement is located by the crown while it is opposite on the former one. Moreover, the new one features a very large 3/4 plate while some bridges were visible previously. If you count the chatons, one was removed. If I let my heart speak, I have to confess that visually speaking I prefer the former movement.
But the new one is very cleverly designed to integrate the jumping date system. It is also thinner what allows to decrease the case height by 0,2mm (9,8 vs 10mm). It is the reason why, even if it is very subtle, the new Lange One appear to be a bit more slender than the former ones (a feeling enhanced by the smaller bezel which enlarges the dial opening).
The other feature is the use of a balance wheel with counterweights which replace the screws visible on the picture above. A proof that the in-house hairspring is also integrated in the regulating organ of the watch.
The new Lange One are available for the time being in 3 versions: PT, PG and YG. No doubt that a WG will join the party later, let's hope that Lange will choose a more daring colour for this watch!
