1011 movement issues???

Hi all,

so I have a constellation with a 1011 movement. I have heard from YouTube watch guys one being the time teller, that the 1000 series movements have issues if they run out of power reserve and need restarting.
Is this true?

should I not let my Connie runout of charge?

This is a link to the time tellers vid I can’t find the other.

I just read desmonds essay with my heart in my throat..... I’m glad I have a 1011 out of all the 1000’s as it sounds like the least likely to give me trouble. And I’m glad it was serviced 1yr ago.......

Pretty much all the issues with the 10XX series movements can be taken care of. If you then keep the watch serviced regularly there shouldn't be any trouble.

It is not like it will spontaneously explode on your wrist.

He can really talk in that video so, start at about 6 minutes. He is concerned that when resetting the day and date on his 1020, the gears are meshing in a bad way and can cause damage. Nothing else that I heard about restarting, just the setting of the day and date.

The 1010 to 1022 are not the same as the 1000 series (which have a poor reputation and partly justified) - here from an Omega document:


The 1020 sets up very well in the main and it doesn't concern me.

On any design with a day and/or date complication there are always quite a few gears under the dial side. This is a 1020 part way through fitting the dial side parts (and yes, you can see some plastic there but, I wouldn't worry about that)


If you have a quickset on any calibre with a day and/or date complication, then only use the quickset after putting the hands in the lower side of the dial (e.g. 6:30) as that way, all these little gears are not trying to change the day or date while you are trying to quickset. If you do that, then I wouldn't be concerned, although, as @ConElPueblo says, don't leave them too long between services. This applies to any calibre and is just a good thing to do - some calibres are very fragile in this area and will give problems if abused.

I hope this helps, Chris

Thanks guys. So basically if I treat it well, don’t change the date after the watch reaches 6:30pm and service it maximum every 5 years I should be fine?

I laughed at the exploding on my wrist comment. Nice work. Needed a laugh today to be honest.

he also says on the vid that he keeps it on a watch winder to prevent the issue happening of meshing gears. That says to me in my mind that they would mesh if it stops and restarts.

what is the movement ref on that one?

Disregard 1020........

Here is a photo of my movement. It took 2 people to remove the caseback. It was on there to stay.

I really appreciate your feedback. Upon having this watch opened by my watchsmith, he stated that from appearances it looks to have been taken care of. There is a slight scuff mark from where the rotor has traveled and he claimed this was due to it needing a service as the rotor shifted over time. He believes this is not happening now and the issue was rectified last time it was serviced. He replaced the caseback seal as this one was destroyed from having the caseback on so tight. I mean tight is good but it took both of us to get it off so......

I think this one will be a keeper. I’m chuffed and it holds time at about +3 ish secs a day. The rotor is damn near silent and free moving and the overall condition is pretty good for its age.

thank you to all that have contributed.
