The last 3-4 6139s I have picked up have all had the same problem...a misaligned daywheel. This used to be something I didn't see too much of. Now it seems like every other 6139 I see for sale floating in the 'Bay has this issue. Not a hard fix, but it seems to be like a plague nowadays. Thoughts??    |

My very first one had that - I'm seeing it more and more - design flaw?

Where I'm seeing it, it's a failure on the daywheel. The disc is moving on the star wheel. Sometimes I can correct for that by firmly holding the star wheel and moving the disc into alignment. The issue then is how to keep it aligned, and to stop it from moving again. I did get one NOS datewheel that was produced slightly out of alignment - it was definitely produced out of alignment since the disc was absolutely not moving no matter what I did. |

I think as time goes on we see a lot of this in vintage watch collecting. They're only getting older and few get cleaned and repaired.
On a personal note, both my 6139-'s are good - no issues.

I am seeing the same thing. The daywheel assembly is not "sticking" during operation...it functions just fine. But the day star and day disc have come out of alignment with each other. With the movement removed and the crown pushed all the way in and held (which locks the day star), I can turn the day disc quite easily with a toothpick. Whatever friction fit these two parts had before is just...gone? Since I have started to run out of replacement daywheels, I have begun using my crystal press to gently tighten them back up after a proper realignment. This is just a phenomenon that I am seeing much more of lately. |
