Thank you for your reply...but still a little doubt

 

Thank you very much Xavier for your reply, i've found this on PuristPro...

"The Caliber L951.0 is, as said before, based on the calibre L951.1 used in the Datograph, but without the date. It is based on it, however it is not identical to it. As always, Lange didn’t just fit a movement into a new case and call it a new watch, but actually modified the calibre L951.1 before giving it its new denomination. The main differences are the new positions of the minute counter notch, which makes adjustment easier, and the switch lever spring, which has been removed from the wheel bridge in the 1815 Chronograph (this is now located directly on the switch lever to make space for the new minute counter notch). Finally, 2 additional endstones have been added on the wheel bridge for a better hold of the zero reset lever, although these are not visible through the back of the watch".

But i don't understand if these modifications are on L951.0 or L951.1...

Thank you and happy sunday,

Francesco.

Good morning, i've a little question about Lange movement L951.0 and L951.1... I know that Lange L951.0 it's the version without big date, used in the old 1815 chrono, but it's also a little evolution of Lange 951.1? I've read a review that explain some d... 

Complicated question in fact.

I would answer you as follows: - first of all, as you can see it with its number, the creation process of the chronograph caliber, the L951, started in 1995. - L951.1 was the Datograph caliber and then the date was removed to create L951.0 used by the 181...  

A small addition

As everybody knows it, the new 1815 Chronograph has a larger power reserve (60 hours vs 36 hours). The changes are here bigger: different balance wheel, in-house spiral, different mainspring, slight change of the lay-out. Despite these changes, It is stil...
