A.Lange & Sohne - Power reserves

Power reserves

Lange & Sohne watches have a wide range of power reserves from:

36 hours:

to 31 days:

But in fact, this range has a huge gap between 3 days (Lange 1) and 31 days.

The new 1815 chronograph gets a larger power reserve than the previous handwind chronographs thanks to a slightly different caliber architecture which gave to Lange the ability to use a bigger mainspring (60 hours vs 36 hours).

Don't you think that time is coming now for Lange to fill this gap with a caliber featuring a power reserve of let's say around one week ? What is your point of view ?

Forget the B-Uhr case for a Lange, they absolutely don't have the will to use it. Fr.Xavier

Lange persuits a different way...

Langes 31 days was actually a test to gain more experience with huge power reserves and very strong torque delivering mainsprings. The new Lange Zeitwerk is further development from the 31 days as the Zeitwerk needs massive torque for the jumping minute a...

I do agree with you.

Count de Monet, I do agree with you about this: I think that Lange will use the power for more sophisticated ways to display time than for various long running watches. As you said, the Zeitwerk is a good example... and what about the idea of using this e...

How could I not think of that !

Certainly ! Zeitwerk's main spring barrel is a real power house and produces even more torque than the 31 day's one, if I recall the article correctly that I read about the Zeitwerk. I believe with such a potent spring in theire hands the next logical ste...

Yes....

But power reserve is not really a strong point for Lange..... The 31 power reserve is not without problems.... I wonder if anyone here owns one so he can share his experiences.... I would like to see an 8 day power reserve..... Hopefully they can develop ...
