A. Lange & Söhne

Hi guys, I have owned a brand new white gold Zeitwerk for two weeks (since 29 Jul). I have made some observations that I hope some connoisseur and a Lange expert can shed light on. (1) The second hand always land on position of 12 o'clock - when I left th...  

There are several models of Langes that have this feature-the 1815 U/D (which I think was first); the Zeitwerk; the Richard Lange PLM; and the 1815 RPC; and most recently the revamped Lange 1. When Lange first released the U/D the press release indicated ... 

This finding is quite unexpected for me...Initially I thought it was just a coincidence that the second hand stop at the same position three times in a row..

I wrote to Lange and got the confirmation that it was not a coincidence!

I must admit I didn't realize this yet, but it works!! So great nice feature !!

I can answer to your second and third point. Lange probably made a subtle evolution of the mouvement recently (over the last 2 or 3 years may be. I can't tell you when exactly) which could explain your first point because with my Zeitwerk, you can notice ...  

It is interesting to know Lange 'evolves' their movements from time to time..

To be honest with you, I didn't know that the regular Zeitwerk mouvement had knew an evolution recently. That's really cool from Lange in my opinion. Best wishes Alkiro

The "arming" is a little side effect of how the mechanism was developed, and my little theory is that it may or may not be observable depending on how the tolerances are set for each Zeitwerk. To understand that, we need to understand roughly how the move...  

And the people explaining the movement features must surely be crazy too. I'm a university professor of psychology - I know crazy when I see it. Thomas

I was thinking exactly that... LOL. It 's fun to see what 'crazy' people write though

You can see a grey gear wheel under the pink disc on the left hand side of your picture. Same grey gear wheel is also existing under the yellow disc, if you look closely at the picture. Both grey gear wheels serve the same purpose: to block and stop the l... 

"During the transition of the Y-bridge to the right hand side into the gap the yellow disc the lower blue wheel is turning very slightly before it is stopped by the grey gear wheel of the yellow disc." < this is what I was trying to describe the primin... 

I understand more clearer now regarding the possible causes for the differences observed between my Zeitwerk and those on the YouTube..

You brought an interesting point to all our attentions. These little details are highly important to us ! Enjoy your fantastic Zeitwerk! Best Moritz

It is certainly an adjustment issue rather than an issue of the teeth profile. Best Moritz

I do not recall a specific mechanism designed to show this feature in the Zeitwerk. Maybe the energy was just running slow to stop it at 60 sec (the jump did not happen). Regarding your point to see my response to skyriding. Best Moritz

before the time switch.. Could I trouble you to take a video of the time switch?

I took this video just now: Zeitwerk No 'Arming'

Zeitwerk No 'Arming' Part II

(1) at the 20th second of the video (i.e. 26 seconds in real time), the Y lever moves..... (2) at the 54th second of the video (i.e. 60 seconds in real time), the minute switches (at the same time, the Y lever moves again) Zeitwerk Movement Video

The jumping is flawless here..
