Breguet

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... 

I own the same watch (3820), my second one -- first was stolen, and my experience is that it should not deviate more than +-2-3 seconds/day (depends on the usage pattern). My first one was 100% accurate and my second one, I acquired it pre-owned, is under... 

But I didn't let the chrono run for 24 Hours, so I can't say nothing about the incidence of the chrono on accuracy. But you're right, when the chrono runs, it has an incidence on the amplitude of the movement. Is it measurable, in terms of accuracy, I hav... 

Nicolas, If watchmaker ever release a watch, at least to me, with this deviation ... +2/-2 should be he target. In respect to the chrono operation, based on the info that I have, here is the summary: a) For cam lever movements. It's a no no to let the chr... 

Will have to check that. The best is that we have some informations directly from Breguet. As for the column wheel, I tried to check with my pics, but I don't see it... Best, Nicolas.

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... 

It gained one sec in the day time, and lost it in the night time... At the end of the month, the watch gained 2 to 3 secs! The magic of these watches is just unbelievable... I should have kept it... Best, Nicolas

as I have the XXI and I had the same issue at the beginning and after I demagnetize it, perfect. I never leave my chrono run 24 hrs a day except the pp 5960 and 5980 which states clearly there is no extra wear and tear.

I own a Type XX Aeronavale, and absolutely love it. I find it an extremely accurate watch, together with my Daytona and Speedy chronos, which are the most accurate watches I own. I find this Breguet, the more classy of my three favorite chronos, though. I...
