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 1815 chronograph.

I believe that the minor changes Alex and Alberto talked about were also applied on the L951.1. Why do I think this ? It is because the number of parts of the L951.1 was at the beginning 390 and then became 405. It is a proof that something changed. Are they exactly the same desbribed by Alex and Alberto's post? Maybe. But I'm not 100% about this.


BTW, your question gave me the opportunity to post this pic:

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...

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, La...
