Expected Accuracy of Type XX
Very happy to be the new owner of a Type XX (3820) in stainless. It's my first Breguet and it's wonderful, but I have 2 questions about the accuracy I should expect from it:
#1) Over the weekend I set and checked it several times and found it consistently losing nearly 2 seconds per hour. That would be -24sec/day which certainly seems excessive to me, but what should I expect?
#2) Second question, for people more familiar with the details of the movement, should one expect a difference in the watches overall time keeping when the chrono is in use versus when it is not? IE, what impact does running the chrono have on accuracy? And what impact is acceptable?
Many thanks in advance!

Is possible with any modern watch, even the more pedestrian (ETA based) ones. It depends how much time the watchmaker is willing to spend to perform the regulation (and, of course, you be willing to pay for his/her time). One example is my LLD. When I got...
