I love my Type XX Aeronavale...

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 feel that a visit to your AD will put your watch within its marvelous timing capabilities.

By the way, I never let the "trotteuse" run all the time, except when I wish to time some event, or just amuse myself looking at the work of my watch, and then I stop it.

Very cordially, Subexplorer.

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...

Here are my answers ...

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...

On mine it is 5 secs per day, which is perfect.

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...

5 is a little too much

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...

+2 / - 2, that is the result of a super ChronoMETRE! ;)

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...
