Omega Constellation won't open

Recommended Posts

Today I got this Omega Constellation I have never seen before, around late 70's? It has kind of octagonal shape and has a quartz movement with quicksetting. As the back is already damaged by the previous owner, I wonder how to open this one without further damaging it as I would like to know which caliber is inside. Appreciate your help guys.

It has a snap off case back. That means you have to pry it open. Do you have a case back knife ? You could also use a knife with a thin (but durable) blade that isn't sharp or pointy so that you won't damage the case.

Look for a small slot/space somewhere along the case back as that is where you should insert the knife. Unfortunately not all watches have that...

You can also try to use a rubber ball and rotate it around a bit to free it from potential gunk and afterwards pry it open but that won't always help.

thanks Chopin...there is no space whatsoever, I guess that explains all the scratches on the side of the caseback. I will give it a go with the squeezeeball, see if it turns a bit.

Hi, i'm a total newbie here. 

I have exactly the same watch, which my partner bought for me as a birthday present about 4 years ago now. 

However, unfortunately i have never worn it because it isn't complete. He thought it would be quite easy to source a dial and hands for the 1330 and this watch case. To complete it. 

But it has proven harder than we thought. Can you help in any way as to where i can get a dial for this watch, hands etc. i have tried many a dial that is the right size as the case however they are not compatible with the case. 

I would love to be able to wear this watch. I love it so much. 

Any help or advice would be gratefully received..

Many thanks in advance.

Welcome and good luck sourcing the parts.

You could send a message to

And ask availability.

Or if you are in the UK then try Cousinsuk.com

You will need to provide the case number which is inside the caseback - probably  395.0802 if the same as the watch above. Alternatively you could try one of these items from eBay which have case, dial and hands:

182937592182

162781970733

    • Cool!   Based on the photo posted above, a good cleaning should be all that is needed. I am not able to discern the cracks in the photo as it is...
    • Thanks I'll check them out !!
    • The second attempt: I took whole movement apart again, cleaned it, oiled it, I also managed to clean all of the jewel holes with pegwood. I also opened mainspring barrel and took out the mainspring. It was quite dirty, I cleaned it, oiled it, and put everything back again. To my surprise, the amplitude looked very good, the automatic winding system seemed fine. The last step was to put the movement in the case. I had trouble with the dial ring and putting stem back (although I think I put it correctly). I took the movement out of the case to check for a problem, but then the amplitude got lower and the watch completely stopped. Since I did not move or touch anything, I suspected it was the mainspring with not enough energy. I gave "external" power by using pegwood and slightly touch the central wheel. The amplitude was normal again. So, my conclusion would be that I have problem with the mainspring: it does not give enough energy for the train to transfer it to the balance wheel. Maybe at first, when the mainspring is fully in tension, but after some time, it is just not enough and watch stops. However, I am not sure where I can buy new 7009 (or 7s26) mainspring for replacement. On the other hand, it could be that the hole made for the barrel arbor got bigger, and now the mainspring teeth are not fully in contact with the center wheel. But I would say that the problem is the mainspring. It is strange however that the watch stopped few days after it fell on the ground.
    • You are correct, I use polident denture fizzy tablets which works well. I have also used an ultrasonic cleaner with a cleaner I mix up. You will never get the hairline cracks completely but you can get them to be way less noticeable.   
    • I like that!!!!!!!!!!!
