The Breitling Watch Source Forums

Some of you may remember that I got this M1 in December last year. I set the correct time in January and after four months it was less than 2 seconds fast. How amazing is this movement?
And since any thread is worthless without pics.

Yep, my airwolf is within 5secs a year...every year. Amazing!

Ditto, B50 appears to be dead on in the last six months, with .5 seconds either way each time that I check... I reset the watch once in ten months after seeing a 30 second discrepancy, which almost caused me to spill my coffee. I eventually came to the conclusion that it was user error of some sort when I was fiddling with it one day. every SQ Breitling that I have owned [about a dozen or more so far] has been astounding in timekeeping.

My emergency have a differenze of 20 second\year.

I've bought a pre-loved Aerospace Avantage in november. Seller told that it gains cca. 12 secs a year. Since november it is cca. 3.5 secs fast, that's 7 secs a year. Not bad. In the same time my Chronomat 41 (B01) looses cca. 0.8 seconds a day, both worn or on winding machine. Not bad either...
