Help removing the tension ring/ crystal in Omega front loader!

Recommended Posts

Hi everyone! 

I have a problem removing the tension ring and crystal in my Omega watch. It is a front loader, so the movement comes out from the front after removing the split stem and the crystal. Mark posted a video a while ago using pressurized air in a syringe to blow out the crystal in a front loader Omega Dynamic watch. My problem is that in my watch, for some weird reason, the crystal is cut (pictures below). Without a chamber to build the pressure up I can’t use his method, so now I don’t know how to remove the remaining crystal and tension ring since it’s really tight. There is also not enough crystal to grip it from the outside.

Please help me!!

If you were careful enough, you could place a thin film of glue (2-part epoxy or cyanoacrylate) on a flat plate and then glue the rim of the crystal to it. Then lift. This crystal will have a ridge on its edge, so you may have to be slightly sudden when lifting.

Thank you!! I will try with try warming up a thin screw driver. If I understood correctly, I should try to burn a hole through the outer part of the crystal in order to access the tension ring and push it out, right?

If that doesn't work I will try gluing a flat plate to the upper rim of the remaining crystall and pull when it dries.

It might be wise to take the hands off first in case you damage them.

I don't suppose I could have the case number? Or even better the serial number found on the back of the case so I could look up something?

In the back of the case it’s written 135019-Tool 106. That’s the only information I can give without opening the watch!

I know we've had this discussion before somewhere? The reference to the tool is a clue for how to take the crystal off.

I have a link that shows the tools they are supposed to have but you'll probably never acquire

No notice also at the link below the other way to take the crystal off is with the crystal lift but there might be a problem which is exactly what you have? If somebody got carried away with the crystal lift Or if it wasn't as close to the case as it could be you do probably break the crystal basically exactly what you have now. But it looks like you do have some crystal left you may be up just grab that squeeze and then Gently try to rotate the crystal lift when it's grabbing really tight and you may a bill just pop it out but you do have to be as close to the cases you can get otherwise you end up breaking more of it off

Because they are crazy expensive. I've never tried the gluing method but I have a feeling that a Seiko S-14 could work.

I have a crystal lift and I’ve tried several times. The claws pop off as soon as it gets right. I think that there is just not enough glass to grab

Right. 

Any approach with no risk of damage to the dial is good. 

Slippage usually  happens when we apply force , burning a hole is to do without any forcing. 

Someone might have glued the crystal on, as result tension ring might also have received some glue. tension ring is made of polymer, so if it comes to it, I would forget about saving the tension ring and remove it in pieces, save the dial.

    • I will try this weekend.  I've tried several times with my cell phone and it's just too small and recessed to get a good picture.  I need to get my macro lens and tripod out and then figure out how to get enough light down the hole in the side of the man plate to  actually show the top of the broken screw. I appreciate the effort and will try and get that pic this weekend.
    • Hello and welcome from Leeds, England. 
    • Hi,   My name is Simeon I am based in Sydney, Australia and have recently got into watch repair / watch making.  I am very much a learner having serviced multiple forgotten watches, some of which were actually successful!   I have a slowly growing collection of watches, mainly old Soviet, a few Japanese and (not pictured) some Raketas, a Poljot Alarm, an Omega Speedmaster Reduced and a vintage (1972) Tissot Seastar.  I like unloved vintage watches, with quirky faces and enjoy bringing them back to life through the simple(!) act of disassembly, clearing and reassembly. I am an Electrical Engineer who also undertook a trade apprenticeship so I am reasonably handy - It's fair to say, I know just enough to get myself in trouble. 
    • ha ha looks like a WMD.....you know I want one now  
    • I took a chance on a non running Cosmotron X8 ("perhaps just needs a new battery" said the advert). Sure enough, I open it up and it has the wrong battery installed (a Renata 344 rather than the correct Renata 386) and the screws holding the battery contact had been sheared off to half a head on both ends. Ho ho, I thought - there's the problem. I got the broken screws out easily enough and as soon as I placed the correct battery in place the balance started. This picked up speed when I reinstalled one side of the battery contact and looked like it was a runner. As I was trying to get the replacement screws in, I did one side but the second was a bit of struggle (hold down the battery contact against its spring while dropping the screw in with tweezers) the balance stopped again. This time it wouldn't start again. 98 percent sure that I didn't stick anything, anywhere important or break it in a mechanical way. The battery was in place for most of the struggling with the contact, so it might have had an intermittent connection which could have upset the electronics. I tried giving it a puff with the blower but the balance doesn't seem to rotate in the normal way, it seems to be held in a static position by magnet. It can be pulled out of this position but spins back and stops dead. This may well be correct for all I know. Anyway, does anyone know anything about these watches and can tell me how I would go about and fault find this? I will be servicing it at some point so should be able to rule out mechanical issues from an old watch but not sure where to start with the electrical part of it.
