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.

In addition: The minute hand is set by turning the crown as usual but the hour hand is set by pushing in the middle of the crown. The hand then will run forward.

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.

You can buff off the scratches. Just tape out the brushed part as that is more difficult to repair.

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

    • It's a bit hard to tell. Looks like the adjust wheel looks grimy tried to zoom the picture but it's a bit blurred. What I would do is put the stem back in and check the enguagement to see if it engages smoothly and isnt binding. Check the squared end of the stem to see if the corners haven't been rounded.
    • I have stripped down the movement completely and will check and re-assemble it tomorrow. Here's a pic of what the stem area looked like. Notice anything wrong ? I'm a newbie with quartzes so I certainly don't.
    • The additional jewels for the 24 jewels movements is for the auto winder, so shouldn't effect the loading of the gear train. The balances I believe are all the same, with some receiving additional adjustment for chronometer grading. I wonder if the GR reference is made from measurements of original springs fitted, and perhaps Omega updates them over time? Perhaps the metallurgy of the springs changed through the years, although all would be white alloy. The GR catalogue also quotes various springs for the Cal 26X range, but I believe these should probably all be the same. There's an argument that running a centre-seconds hand adds to the load (it will typically reduce amplitude by something like 5-10 degrees when adjusted) but that's not enough to significantly affect performance. I see that on the Cousins website they list three different springs if you search for a Cal 565... On my Cal 552 I have a 1.10 x .105 x 360 (11) spring which reaches 300 degrees amplitude, if that helps.
    • oh well, can't save them all.   But I try
    • The watch has been returned to the customer. You are correct someone had been poking around with this movement most of the screws were very badly bruised the hairspring had been badly damaged & the balance staff broken.
