Post subject:  New Chronomat GMT question

Hello everyone,,
New to the forum: a week ago, I took delivery from an AD of a new Chronomat GMT, all steel, AB041012/g719ss. Now twice, after a full wind (40 turns) and wearing the watch 24/7, it stops after about 2 and 1/2 days of wearing. I was under the impression that the self-winding feature would sustain operation; otherwise, the watch keeps perfect time - I have not operated the chonograph feature while wearing. Any suggestions?

Assuming you're active and your movement isn't impaired in some way, then your watch should keep running if you're wearing it 24/7. The 2.5 days it runs for is close-ish to the 70 hour power reserve of the B04 movement (which it would've got when you manually wound it), so it looks like the self-winding mechanism isn't working. Probably a trip back to Breitling I'm afraid.
