I think it is a great evolution.
First of all, it is not surprising, the changes were expected: the case diameter and the increased power reserve, especially after the new 1815 chronograph.
Secondly, the watch is really beautiful. Its enlarged case makes it slender and all the original Datograph spirit is preserved like the triangle created by the date display the subdials, the PR indicator remaining very discreet.I consider this new Datograph as a very worthy evolution with more than welcome improvements which will give a new dynamic to this watch.
Best.
