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.

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

    • A simple cheap alternative would be to make a case back from a CD (Compact Disc) I have a habit of stringing up CD's in the garden. After they have weathered the coating comes off and they are clear but not as transparent as a watch crystal. Also the ones I have had are 2 part laminates which easily separate after weathering. I have used these in the past for emergency crystals in cheap watches. In this case you could use a new CD. Cut out a circle which fits tightly into the case. Cut another circle which fits over and to the overall diameter of the case and glue the 2 together. Alternatively just cut a circle which fits the overall diameter of the case and glue it on but glue it all around so to seal it. Trim if necessary with a file, sandpaper etc. It should not scuff up as quickly as a crystal. I use scissors to cut after the CD has delaminated ie one half but I use my scroll saw to cut a full thickness CD
    • Hello JohnR725 I appreciate very mutch all the good help I have got during this watch repair!   But that is why I usual stick to mechanical watches, and that this was just for a really good friend. And that I usually dont do quartz.     Thanks to ya all...    :-) JohnR725  
    • Thanks Guys, oldhippy, when you grow up with the poisonous creepy crawlies you learn to know what to watch out for and respect your surroundings. We've had several Tiger Snakes, that we've known of, in our yard over the last 18 years, which isn't bad considering we back onto a creek. And that same creek brings us wallabies and water birds, so that's a definite bonus. Too much sun exposure is more of a worry, and killer, in this country ecodec, It's the making of things that drives me Hey Geo, I didn't have the brass for it so... A friend of ours gave me the, then rusty, bobbin winder for an antique sewing machine to turn into the drive wheel. I drilled a shallow hole in the bottom of each foot and inserted a crepe rubber plug that just protrudes by less than a mm. This stops it from moving in use, while not making it 'wiggly' on the rubber. Here's a view from the other side showing the adjuster slot for the belt tension and, if you look closely, you can see a nail that goes through both clamp jaws (tight in one and free in the other) that I hook the 'tail' of the turns under. This makes the turns very secure, even before tightening the two wing nuts on the clamp.
      Have a good night guys. Cheers
