Some observations regarding the Zeitwerk..
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 the Zeitwerk to wind down completely by itself on three occasions, the second hand always stop at the 12o'clock position. Is this mechanism similar to that in the latest version of the Lange 1?
(2) No noticeable 'arming' of the minute disc - I noticed from videos that were uploaded on YouTube, that the minute disc would move a little, a few seconds before the minute switches. In fact, according to Mr Peter Chong's explanation on the mechanism, this 'arming' process would occur about 8 seconds before the minute switches. However, I could not observe this 'arming' process in my Zeitwerk. The minute disc simply switches exactly at the 60th second (i.e. 12o'clock).
(3) There is a structural change to an observable part of the movement - I have highlighted this part using a forumer's Zeitwerk (Alex83; I hope you don't mind me using your photo as a reference) and a photo of my Zeitwerk. Its the part where the blue screw resides. In my Zeitwerk, the part with the blue screw is not a single piece with the part above it.
Thanks!

I can only speak to your first question.
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 ...
Thank you for your reply..
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..
It's what happened to me.
I wrote to Lange and got the confirmation that it was not a coincidence!
How great!!
I must admit I didn't realize this yet, but it works!! So great nice feature !!
Dear Dan
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 ...
Dear Alkiro, your macro shots are amazing!
It is interesting to know Lange 'evolves' their movements from time to time..
Thanks Dan
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
With response to 2:
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...
These macros are crazy.
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
It's funny...
I was thinking exactly that... LOL. It 's fun to see what 'crazy' people write though
The "little priming jumps" are due the grrey gear wheehl under the yellow disc
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...
You worded it better than me -
"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...
Thank you skyriding and COUNT for the detailed explanation..
I understand more clearer now regarding the possible causes for the differences observed between my Zeitwerk and those on the YouTube..
Thank you for your observations!
You brought an interesting point to all our attentions. These little details are highly important to us ! Enjoy your fantastic Zeitwerk! Best Moritz
Agree to your points
It is certainly an adjustment issue rather than an issue of the teeth profile. Best Moritz
Your observed stops at 60 are more a coincedence, imho
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
Interesting tat your zeitwerk doesn't "arm"
before the time switch.. Could I trouble you to take a video of the time switch?
This video is taken 6 seconds after the switch...
(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
