A. Lange & Söhne

This watch is no longer a secret, but you are certainly many waiting and hoping to see it and know more ! As you already know, Amanico, Foversta and myself had the pleasure to attend a presentation of the new for 2009 A. Lange & Söhne Richard Lange Pour l...  

You perfectly explained that beneath the simplicity of a 3 hands watch, there is a complex caliber full of technical features. Fr.Xavier

Can't wait to see what Lange will present in less than 3 weeks, now. This PLM was above my expectations, indeed. For its understated Beauty, and its mechanical sophistication. Thanks to you, now we better understand how interesting is this PLM, mechanical... 

thanks a lot, great report for a truly dream watch greetings from France

The more I read your posts the more this watch fascinates me.Congratulation guys for the wonderful reports.All the best.

Thank god this watch is not available yet, becuz with all the post we've read here and the beauty of this watch, it would have been very hard to resist K.

Now I need to spend some time with this beauty. Thanks again. Bill

A really great job. Thanks for sharing with us this magnificient watch. Two weeks ago, for the first time in my life and thanks to Nicolas and F. Xavier, I could take in my hands and admire three large pieces of Lange. I never thought that these watches c...

I'm so so sold!

Thanks for sharing with us this very wonderful masterpiece from the House of A. Lange & Sohne! As always, they have gained my respects, and this time round even more so, because it's the 2nd piece in the family of the Richard Lange collection, in which th... 

Fascinating read. And for explaining things in a way a noob like me can understand.

and your personal view. I appreciated them a lot as it was a pleasure to read. Oliver

you, FX and Nic do fantastic reports I have been eyeing RL, can only dream of RL Anny and now this PLM ... this keep my WIS alive ...LOL

for this extraordinary article, which has made at least some parts of this movement clear to me. Undoubtedly this is a ground-breaking achievement in sophisticated movement construction, and if you consider the precision it requieres from the manufacturer... 

Do the other PLM's make use of the same full winding locking mechanics? I think the old Tourbillon PLM uses a different low winding locking device but I am not sure. And I think this Richard Lange Pour le Merite uses a different seconds- hack mechanics (h... 

computer renderings (and the graph) you used in your post? Edwin

No message body

the result of spending too many years on a bicycle, but would there not be some 'play' in the chain after time and if not, how do they make sure that would not happen. If it does, then that would affect the time keeping ability of the watch. The concentri... 

Unlike the bike, in this case the chain is constantly pulled by the mainspring so the tension is always there. And if the tension is lost, probably the ratchet wheel on the main barel needs to be tightened.

It is absolutely astounding in every regard. Thank you for this report.

Fascinating watch and a great job on this truly "in-depth" review! It's really a rare occasion to find a review that goes beyond just taking a macroshots of the watch/movement here! A question regarding the winding - if I understand correctly the winding ... 

Congratulations and thank you for this article. It has made clear to a great extent the technical refinements of this marvel, although I am still mystified by how the torque on the fusee and the wheel train can be kept constant whilst winding the main spr...

Constant rate equals more precision. Constant rate equals more accuracy?

Very informative and a pleasure to read, I can't wait to see it in reality ! Regards, SLPW
