What is an acceptable deviation in time over 24 hours for a Breitling automatic watch. I’m going to measure mine again but it seems to be loosing approx 14 seconds a day. I’m not using an app for this but setting it to a time on a website and then comparing it 24 hours later. Seems to be out but not sure what the tolerances are? |

The COSC limits are -4 to +6 seconds per 24 hour period! Good Luck! |

Thanks it’s only 4 months old from Breitling and it’s loosing 15 secs a day. I’m noticing it’s loosing enough time over just a few days for me needing to adjust it. |
